In simple terms the idea starts from a common praise of the fediverse … that it enables posting between Twitter and Reddit and that it is open. Well, how about we build Reddit and Twitter clones just with FOSS, open APIs and cross posting features?
Isn't that opening the door for future enshittification? Like as soon as Lemmy/Mastodon reach 100k users, a big corporation buys the only instances (as there is no federation in this scenario) to the admins, and turn it into a corporate product? What's preventing that without federation?
