I started using Usenet in the early 90s and have continued to use it until today. Modern clients are very convenient and easy to search and filter out whatever you like. So no, if you aren’t too lazy to learn your tools then it is more than sufficient without some dystopian social media tier control of the protocol.
Ultimately Lemmy isn’t any better than Reddit because your “account” is tied to a server, so it isn’t truly censorship resistant. It can easily get as bad as Reddit is with the ham fisted censorship at the whim of some misanthropic moderator.
Nostr is certainly the future once it matures a bit more and becomes more user friendly.
