As one of the most active users of notabug.io: you're not wrong. There's no hypergrowth.
But the tech has real promise and that's the story here. Of course 'alternatives' get the scoundrels first so criticizing it on that merit is a bit generic.
There's value in federated systems with a p2p overlay even if they're not attracting the money driven crowds. You can't post sci-hub links openly on reddit. You can't even discuss how to handle DRM and bypass it.
Centralized systems are always going to go through the same lifecycle after they reach a critical mass requiring real money. It's not pretty. If anyone can self-host from home or even contribute hosting by visiting with a webrtc enabled browser it benefits a lot of groups pushed out for perfectly cromulent reasons.
However, snew.notabug.io is a mirror of the corresponding Reddit posts w/o censorship, which makes it not an alternative! Shenanigans identified!
