I wonder, though, could this be considered an unconstitutional bill of attainder? That's an act of a legislature declaring a person, or a group of people, guilty of some crime, and punishing them, without a trial. Article I, Section 9, iii: "No Bill of Attainder or ex post facto Law shall be passed".
That’s been my thought since the TikTok ban as well. It was meant for people, but this for sure seems to meet the spirit of the prohibition. Does it actually violate it? We’ll have to see once the cases work their way through.
