Back when I was active on Usenet it was considered pretty normal to have house rules for any newsgroup, you were also expected to refrain from posting long enough to notice and learn the unspoken customs (this was called "lurking").
Nowadays people see it as an orchestrated attack against free speech, shout references to 1984, and threaten to move elsewhere.
Yet the ones asking us all to behave politely are called "hypersensitive"?
@orionwl Exactly, I like the choice we have. If someone disagrees with a particular instance's rules they are free to move to a more permissive one. No one is forced out of Mastodon, only in certain parts they are asked to keep a given level of decency.
