Most of the time when people say they have an unpopular opinion, it turns out it’s actually pretty popular.
Do you have some that’s really unpopular and most likely will get you downvoted?
It is not what is called “single point of failure “. Usually if “single point of failure “ fails, the whole thing fails. I am on kbin and experience zero failures.
If they were to actually go down (the current failures do not affect the backend), all of the communities they host wouldn’t be usable anymore, taking down a large portion of the Lemmy/Kbin communities.
