you telling me that I’m not allowed

You are not your Lemmy account, and you are specifically not one single Lemmy account. If you don't like the policy of an instance, you can try to change it or go somewhere else. Ok right, in the attempt to influence policy, you can play the 'you telling me that I'm not allowed'-card.

Now that I think about it, the most uncensored Lemmy experience is being logged out. Every content is visible, no middle man can hinder you to visit these sites. It's a bit like when a public library decides to organize their books into separate rooms. Would you call that censorship because you have to walk between the rooms to access all the content?

Censorship would be fitting if certain content would be erased from the library. I think that's only possible on Lemmy if all instances agree.
