just like folks still on Twitter, Facebook, and Reddit?
As I said, Lemmy is federalized. Jumping from Twitter to BlueSky/Mastodon or Reddit to Lemmy is difficult due to the network effect. The people you want to follow aren’t posting on BlueSky/Mastodon/Lemmy because there isn’t an audience there. It’s a self-fulfilling prophecy.
However, Lemmy is federalised, that means you can change instances without loosing access to the people/content you follow. Sure, the fediverse isn’t immune to corporate takeover, but it is more resilient.
Migrating from Reddit means you loose access to all Reddit content. Migrating from .world to, I don’t know…, .ml means nothing sense you can still access .world’s content.
You need the plurality of site content
I wouldn’t say plurality. If the biggest instance only had 10% of total content, that 10% being taken over by a corp wouldn’t kill Lemmy. That 10% would be too little to perform the drawbridge strategy and so people could migrate to a different instance and access the same content.
No it’s not. If a single server holds a critical amount of the fediverse’s content, they can enshitify.
The reason why the fediverse is resilient to enshitification is due to the fact that it makes migration less painful: If you want to abandon Xitter, which is centralized, you will be unable to access Xitter’s content, which is why it took so long for people to abandon it; but if you want to abandon… let’s say… mastodon.world, you can just make an account on another instance and still access the same content. For enshitification to occur, user’s must be locked in, the federation stops that.
However, this system has one major vulnerability which can completely subvert the fediverse’s ability to resist enshitification: centralization of content. If one instance holds a critical amount of content, they can pull up the drawbridge, that is, de-federate from all other instances. You might think this would upset the users, but it wouldn’t. Most wouldn’t know what federation is, all of mainstream is on the default instance, only the computer nerds are on other instances, so if suddenly, the default instance de-federated from everyone else, and thus becomeing a walled garden just like Xitter, few would notice and fewer would care. And now the default instance is centralized just like Xitter and the enshitification cycle repeats.
If you want an example of this look no further than Gmail. More or less 95% all emails are Gmail. If Gmail de-federates from your instance, you are removed; that means Google can basically dictate what other instances are and aren’t allowed to do. If you do something Gmail doesn’t like, they can de-federate and you instance is now basically useless, since you can’t email 95% of people. Gmail could easily kill Proton Mail by de-federating.
