The alternatives are that you find other servers to post on, or you go back to corporate-controlled websites (which would honestly be silly with the amount of Lemmy instances that exist now). So if you commonly find yourself at odds with the subject matter, you can post elsewhere. I’m sure there’s some conservative/other flavor Lemmy communities out there that function the same way. That’s the beauty of the open internet, but it also means people can ban you for whatever reasons they want and there are no repercussions.

So you wade in at your own risk, which you’re doing either way because there is no strict corporate structure overseeing the rules. It doesn’t mean that every decision people running those sites make is suddenly good, but you at least have freedom of choice when it comes to what servers and communities fit for you. Just like instance runners like myself can also decide which servers to federate with, while blocking others.
