Not to mention search itself being fundamentally broken in Mastodon - there is no way to search all servers at once, you will always only see what the instance you're searching on has ingested into its cache. There's no trending topics or if there is, it's outdated and/or unmoderated. On top of that... instance mods powertripping is another issue. I don't care on which side of that godforsaken war in Israel/Palestine two different instance moderators are. But I do care when one of these morons drags in their user base into this bitch fight and decides to defederate from the instance ran by the other dude and suddenly I can't interact with a follower any more, I don't even get a warning "hey, you can't see posts from XYZ any more because their instance defederated from ours". While I'd love to see Mastodon succeed at least in survival, it suffers from a bunch of very fundamental design and concept issues.
