What? I kind of get that some censorship can be illegal. But if I privately choose to think that the views of X are idiotic, and kick them away from me because of that, that's my call. That's not censorship, that's me choosing.

As someone else implied, the private company can do as it please (within the law), and if getting chucked off the platform is a problem, then there is a monopoly problem to be dealt with, not a censorship problem.
