Trump’s Defiance of TikTok Ban Prompted Immunity Promises to 10 Tech Companies

Trump’s Defiance of TikTok Ban Prompted Immunity Promises to 10 Tech Companies

US attorney general Pam Bondi has told at least 10 tech companies, including Apple, Microsoft, Amazon, and Google, that they have “incurred no liability” for supporting TikTok despite the federal ban on providing services to the popular video-sharing app, according to letters disclosed on Thursday.

Under orders from President Donald Trump, Bondi has refused to enforce a law passed by Congress last year that classifies TikTok as a national security risk because of its ties to China and bars companies from distributing the app to US consumers.

TikTok can dodge the ban by reducing the ownership Chinese entities have in its US operations, and Trump has described those negotiations as ongoing. But constitutional experts have questioned the legality of executive orders by Trump that delay enforcement of the ban as those sales talks drag out.

Early this year, TikTok disappeared from the US app stores of Apple and Google after the ban went into effect. But despite the law still being on the books, TikTok returned to the stores after just a 26-day hiatus. Several media outlets reported at the time that Bondi had written to Apple and Google promising they would not face prosecution. But the letters had not been publicly disclosed until Thursday.

Silicon Valley software engineer Tony Tan had sought the letters under the Freedom of Information Act. The Department of Justice initially claimed it did not have records matching Tan’s request. He sued the department, which ended up releasing several letters to him on Thursday.

A Justice Department spokesperson did not immediately respond to a request for comment.

The disclosures show the first letters were dated January 30 and sent to four companies—Microsoft, Google, Apple, and content delivery network provider Fastly. “Google has committed no violation of the Act and Google has incurred no liability under the Act during the Covered Period,” then-acting attorney general James McHenry wrote. “Google may continue to provide services to TikTok as contemplated by the Executive Order without violating the Act, and without incurring any legal liability.”

Bondi took over as attorney general in early February, and days later Google and Apple separately wrote to her, according to the released documents. In responses dated February 11, Bondi wrote that “the Department of Justice is also irrevocably relinquishing any claims the United States might have had against” the companies for violating the TikTok ban.

After Microsoft inquired, it also received on March 10 a letter “irrevocably relinquishing any claims.” Similar language was included in letters dated March 10 to Amazon, data center company Digital Realty, and cell phone service giant T-Mobile.

In early April, Trump extended the negotiating window for a TikTok sale and further delayed enforcement of the ban. That led to a round of 10 letters on April 5, including to content delivery provider Akamai, cloud vendor Oracle, and TV maker LG. Among those letters, only the ones to Apple and Google mentioned the “irrevocably relinquishing” vow. But three days later, Bondi sent a new version to Microsoft including the language.

Microsoft and the other nine companies didn’t immediately respond to requests for comment.

Tan, who obtained the letters, last month filed a lawsuit against Google parent company Alphabet accusing it of withholding information about its decision to continue distributing TikTok on its Play store. (Google previously declined to comment to WIRED on the suit.) He worries that the promises from Bondi are non-binding, and that Trump or a future president could end up prosecuting tech companies that are currently supporting TikTok. Google could face billions of dollars in fines if found in violation of the ban.

plunges down over 3 miles (4.9 km).

For decades, scientists assumed that this literally continent-sized block of ice rested on an expansive and stable chunk of Earth’s crust known as a craton. A team of researchers has now complicated that picture—mapping a vast, interconnected geological structure that fans out from a troubling “tectonic deformation.” Beneath this ice sheet, thinner and more geologically recent slices of crusty lithosphere fan out into hidden valleys called “pull-apart basins.”

These basins—30 elongated wedge-shaped valleys in total—constitute an entirely new, continental-scale geological region underneath Antarctica, in fact, one which the researchers have named the East Antarctic Fan-Shaped Basin Province (EAFBP). But it’s how they likely formed that has now caught researchers’ attention.

To put it bluntly, it turns out that about 90% of the planet’s fresh water ice may not be on solid ground. Geologist John Goodge called the team’s findings “provocative” in an independent commentary on the new study, published Thursday in the journal Nature Geoscience.

“East Antarctica is typically considered from seismic tomography and geodetics to be ancient and generally stable,” according to Goodge, who studies continental tectonics with the nonprofit Planetary Science Institute. “[But] something else is going on at depth.”

Continental divides

Goodge speculates that this seemingly “coherent pull-apart system,” as presented in the new study, might help explain a variety of mysterious heat and water flows beneath this ice sheet’s surface, like that enormous subglacial lake identified in 2016 or some of the hundreds more like it.

The study’s authors, led by geophysicist Egidio Armadillo at the University of Genoa in Italy, agreed: “Because these basins underlie about half of the East Antarctic Ice Sheet, they are likely to heavily influence both ice-flow and landscape evolution,” the researchers wrote in their study, also published Thursday in Nature Geoscience.

Armadillo’s team, coordinating across Europe and the U.K., developed their new understanding of Antarctica’s hidden bedrock via an exhaustive set of sensory data. Gravitational and magnetic anomalies were mapped via low-altitude airborne surveys. Ground surface features were mapped with seismic tools, using sound waves that vibrate through the ice and ping back information about subglacial landscapes in 3D.

Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica
                The East Antarctic Ice Sheet is almost unfathomably huge. Covering about 75% of the entire frigid continent (nearly everything on its side of the Transantarctic Mountains), the sheet covers about 3.9 million square miles (10.2 million square kilometers) and extends down 1.4 miles (2.2 km), on average, before coming into contact with Earth’s surface. At its deepest, the ice plunges down over 3 miles (4.9 km).

Credit: Nature Geoscience All of this data—the fruits of “multi-national efforts to image within and below the ice sheet,” as Goodge put it—had already revealed that regions of the continent were “undergoing more rapid movement and ice-mass loss than previously recognized.” Armadillo’s team merely helped to explain why.

 The mechanism Armadillo and his colleagues proposed for the formation of these fan-shaped basins is called “distributed rotational extension.” It involves points called Euler poles around which tectonic plates pivot or rotate rather than smash into each other or pull apart. The result is a bit like decks of cards being spread out on a table, thinning out the stack of Earth’s crust as it moves. An icy situation Goodge took pains to spell out the basins’ implications for melting Antarctic ice due to climate change and the risk of rising global sea levels.

 The mere existence of these basins, he wrote, “could introduce widespread, systemic instability to the East Antarctic Ice Sheet” via thinner layers of Earth’s crust and more heat flow from below. On top of that, a series of fault-line “troughs” documented between the basins appear “tailor-made to promote outward flow of ice streams from the interior” into the world’s oceans, he said. That said, the team’s findings are unlikely to end this debate. As Goodge noted, Antarctica is “the last continental frontier of scientific exploration.” It’s still a very mysterious place, one that’s challenging to study given its inhospitable temperatures and extreme geography. Its “cryptic subglacial geology” might stay that way for a while.      #Scientists #ContinentSized #Geological #Structure #Hiding #Beneath #AntarcticaAntarctica,Geology,mapping,Plate tectonics

Ahead of this year’s World Cup, Amnesty International warned that millions of fans attending the tournament are at risk of attacks on their human rights, especially in the United States. The organization added that the tournament, which will also be held in Mexico and Canada, could take place amid severe restrictions on freedom of expression and peaceful assembly.

In a report titled “Humanity Must Win: Defending Rights, Tackling Repression at the 2026 FIFA World Cup,” Amnesty outlines a range of risks faced by fans, players, locals, and media attending the tournament in its three host countries.

In the US, where three-quarters of the World Cup matches will be played, the report finds there is a “human rights emergency” characterized by racial profiling and mass detentions by agencies such as Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP).

“This World Cup is far from the ‘medium risk’ tournament that FIFA once judged it to be,” the organization wrote. “The joy that fans hope to experience over a six-week celebration of football is overshadowed by the reality of violent arrests, mass detention,” and other abuses.

Earlier this year, then-acting ICE director Todd Lyons said ICE would be a “key part” of security during the World Cup. Since then, the extent of ICE’s role has not been fully clarified. But in May, Department of Homeland Security officials told NBC News that ICE is offering its personnel to local police departments to help with security during World Cup matches.

Amnesty International’s report indicates that in Mexico federal authorities have announced the deployment of around 100,000 security agents, including members of the army, in response to high levels of violence. According to Amnesty, this decision increases the risk for those demonstrating, including a movement of searching mothers who have planned peaceful protests in the vicinity of the Banorte Stadium (formerly Azteca Stadium) in Mexico City to demand transparency, justice, and reparations for the 133,500 disappearances registered in the country. This initiative is expected to be joined by other mobilizations during the tournament, linked to access to land, water, housing, and criticism of gentrification.

In Canada, the report notes, there are fears that the country’s housing woes will lead to unhoused populations in host cities like Toronto being displaced by World Cup activities.

When Amnesty released its report in March, the organization claimed only four of the 16 host cities had published plans for the protection of human rights during the tournament. It recommended that host cities avoid the use of military forces in civilian security tasks and stressed that local authorities should ensure that World Cup events and venues were not subject to immigration raids.
