Add the fact that lemmy.ml and others were/still are doing applications for sign up instead of an automated system. I applied twice for a .ml account and never got a single response, not even a denial or "your application is being processed". I have no idea if my application was ever even seen.
On the other hand, I signed up to lemmy.world and kbin.social in minutes and have been using them ever since.
Adding to what others have said, opposing viewpoints are GOOD. Well reasoned opinions should be encouraged. I don't want to end up in another curated echo chamber built by someone else. Add the tools for users to block an instance and for blocks to work better in general. Give us the tools to decide our content. Leave the curation up to the users.
Otherwise you'll just end up with everyone spinning up their own instance and building a million individual echo chambers(tho it wouldn't be bad if there were more instances lol)
