That doesn’t make sense. ”Mastodon” isn’t a single entity. My just-for-me self-hosted instance certainly doesn’t have censorship.

You are literally one search query away from it making sense:

There was a huge uproar about it a couple of years back.

EDIT:

Gab was "banned" in that the vast majority of instances blocked it and blocked any other instance that didn't do the same.

If that's not censorship, I don't know what is. You can have your sandbox but you can't play with others unless you accept their censorship rules and politics.

I assume you mean a specific instance running the Mastodon software, most likely mastodon.social?
