Attention ...Law firms and funders :-) this is exactly the kind of cross border data transfer case where billions in penalties and settlements, and major fees are realistically on the table. :-)
Clearly they did not transfer only US users but for sure EU users data. I guess HN here too? This would violate GDPR especially Art. 48. Companies can have fines up to 4% global revenue and mass collective damages claims in EU courts. Best fill in the Netherlands and or Ireland.
Coordinate with EU GDPR actions and U.S. discovery rules, that are the strongest in the world. Get the internal emails...Millions to be earned...
For US users you are out of luck. The US is the country of loopholes, and although these subpoenas were not from a judge, several agencies can issue them, under multiple jurisdiction laws.
Brute forcing the 14 million undocumented immigrants in the USA is no doubt going to end up a crime against humanity seeing how they've handled the last year.
There's 5 million+ citizen kids with undocumented parents in the USA.
The foster system in the USA has 800,000 kids
The administration is incompetantly evil if you have any sense of scale and understanding of historical reality of other attempts to move that many people.
