The moderators of online communities have every right to manage the content of those communities as they see fit, as long as they're within legal bounds.
That said, individuals also have the right to call said moderators a bunch of clueless asshats when they make dumbass decisions, as long as they're abiding by the policies of the space where they're saying it.
Microsoft banning the word "Microslop" from their Discord isn't censorship is well within their legal rights, but they are a bunch of clueless asshats for thinking that it was a good idea.



In the context of the 1st Amendment it's not illegal censorship, as private entities aren't bound by the 1st Amendment in their own private spaces in the same way the government is. But in a more general sense you are correct, I think my brain just strongly associates accusations of censorship (in a US context at least) with accusations of 1st Amendment violations. I'll adjust the phrasing.
