And absent it being an actual threat (which it's clearly not), I don't see what your issue is. Kanye West is well within his rights to criticize Jewish people the same way that literally every woke person is within their rights to criticize, nay, demonize white people these days on every social media, corporate media platform, and news outlet these days.
In any case, you use very generalized arguments, hard to discuss them. If you think he is "criticizing" Jewish people (which does not sound like it to me) - do you think it's not an antisemitic thing to do? (To pre-empt your counter-argument... yes, criticizing all white people is also racism/bigotry.) Treating a race, a nation, all followers of a religion, etc as a uniform group that can be subjected to some "criticism" is not an idea that's valuable to the open society. Again, I don't think people should be immediately banned for expressions like that.
If you think we need a "free speech" app filled with these "valuable" ideas - that's fine, just don't expect that it will be a space for discussing opposing views. Places like that always end up on either extreme right or extreme left.
I am not advocating censorship, but want to point out that your hopes might be misplaced. The illuminating ideas this kind of a free speech platform usually attracts rarely go far beyond bigotry.
