You lying to yourself or have unfounded expectations.
Nobody mentioned any expectations hm...
Everything on Mastodon is in plain text, there is no encryption, and servers get mirrored.
That's 100% correct, and I think it's important to explain that to non-techy users.
It’s only the login info that stays with the instance [...]
Technically yes, but I'd cut the "only" because login info includes the users email. So in case of a raid or data breach, I'd like to know about it.
The entire point of why Mastodon was ever started was censor evertbody that has the wrong opinion. Twitter wouldn’t delete people because of what they believe, so Mastodon was developed to ban IP address so only approved speech could exist on the internet as far as they are concerned and can avoid ackniwledging the real world. A high number of people on there, especially the admins, live in cult
I don't know what places on Mastodon you've visited, but that's not the point of Mastodon or the Fediverse in general at all. But we don't have to start a discussion about that since you seem to already have made up your mind about it.
I get your point. Then, why not start your own instance with rules that you approve? I know, easier said than done, but that's the nice thing about the Fediverse. Next to the general purpose instances, there are many "themed" ones with focus groups such as musicians, journalists and so on.
