Can anyone recommend a good one?

I'd like one that can kinda "save" my progress not only locally. Maybe an app account or something that integrates with a cloud service?

I had an ancient one very early in my smartphone days, but as I lost/had my phone stolen I would lose all my progress and miss the pages of the books I was reading.

Not willing to give them ideas so fast.

That's something that popped in my head as soon as I started in here, not so long ago.

But there's nothing to prevent that, right? I mean, Meta could very well create a meta instance on Lemmy or Kbin or Mastodon or in all of them, bring a bunch of users, sprinkle in some ads because why not.

Sure, they could be defederated from more restrictive insfances. In the bigger picture, every other instance could boycott them, but they would surely federate among themselves (Elon meets Mark, ugh). They also have all the computational power and would have no problem being the largest instances in the Fediverse.

Then what? Is that feasible? Probable? My utopian future about a free, descentralized Fediverse is a lie?
