I could see a legitimate service being made out of something like an extra private lemmy, or a lemmy with additional features. Sort of like you'll see these suites of services from Proton or Nord. Yeah, i can set up my own SMTP server, even encrypt my data, but it's a lot easier to pay a few bucks to have a reliable service do it.
With federated services eventually becoming mainstream, i wouldn't be surprised to see some companies offering packages that do things like provide additional privacy or larger amounts of storage.
Or like I'd imagine sustainable video hosts will have to monetize somehow just to pay for the storage space.
I'd say it's more that we've been paying out the nose in the form of offering up our data and digital autonomy, and by allowing not only the Internet but our societies at large to degrade and polarize. We've paid dearly for our 'free' services, in the case of the US with everything from our reproductive rights to our connections with our own families and communities.
I'd much rather pay the price of an extra latte now and then for real internet communities than deal with actual Nazis and orbital Teslas for some shitty undermoderated ad feeds infested with trolls, AI, and literal societal saboteurs on the payrolls of Putin and Winnie the Pooh.
