I'm here, because despite the lack of a dislike/downvote button, Nostr offers unrestricted free speech. Unlike Lemmy, which I also use, Nostr posts can't be deleted easily by a mod (which on Lemmy can be anyone who volunteers/creates a community + admins).

Deleting fights spam, but is often abused for political reasons (too humane, too communist, too capitalist or too nazi for mod), which creates circle jerk communities, where everyone just posts what the mods want to hear, instead of actual conversation/discussion.
