Summary: The above is important because of the timing. After 5+ years of pension fraud at Sirius 'Open Source' the company enrolled staff without paperwork/signatures and barely with any consent (in late 2016); to make matters worse, a few years ago it upped staff contribution levels without increasing its own, in effect forcing staff to send even more money (one's own money, not the company's) into this dubious pot with uncertain future.
TikTok - like Julian Assange - does not enjoy any protections of the First Amendment and since it's not a person it would lack these protections as an American company, too
This previously happened in Texas, where companies perceived their presence (in any form) to be a liability as patent trolls could drag them to friendly courts and win "damages"
