No, no, you can't do that. Than they'll come after you and claim how you're not free, you don't support free market and whatnot. Banning is tool for them, but not for you.
Couldn't people just say "but Instagram" is just TikTok? Is it really the "same thing" just, because the same people have control, if the algos, servers, content, moderation/censorship, and promotion are different? Like BlueSky, Twitter, and TruthCentral are all the same thing? Or if we want the "same company" company Allo and Hangouts? I mean everyone loved Allo, right, you can have that one.
