I don’t want random posts to appear in my feed from communities I haven’t subscribed to, but I want to have a feature that shows me suggestions for communities when I ask for it. That’s a big difference. Right now it’s (too) hard to find these communities.
There’s no need to post a hateful comment like that. If you don’t like it, fine, then don’t use it. It’s OK to say why you don’t like it, but don’t call it garbage.
