It's the only way they get to go on believing their cult, by silencing everyone they disagree with.
From that perspective, it's not so different from leftists censorsing and deplatforming.
Since that's not possible on nostr, they mute anyone who disagrees instead.
The result is the same. Continue living in lalaland echo-chamber and circlejerking with your buddies believing you're all the best and brightest.
Oh well.
