> The constitution explicitly bans bills of attainder so any law targeting a specific person or company will be struck down.
The law must be both specific and punitive to be a bill of attainder. A law can nonpunitively regulate a “class of one” without being a Bill of Attainder. See, Nixon v. Administrator of General Services, 433 U.S. 425 (1977). [0] So, it is not quite accurate that “any law targeting a specific person or company will be struck down”.
OTOH, a “TikTok ban” based on asserted prior misconduct would pretty surely be seen as punitive.
