It would ruin memes the moment that happened. You already see it on like reddit when Karma gets too important. All the main meme subs are filled with such junk. I have never seen anything unfunnier than r/funnymeme
This is what scroll did, before they got bought by Twitter. Same for coil, who shut down, by the people behind then still seem to be working on something. See https://webmonetization.org/
I don't know much about statista, but yeah the steam numbers linux users love to cite regularly fluctuate by like 25% and windows usage has been shown to basically depend on how active the chinese market is.
I mean it's one thing when you bring together a bunch of services that have no interest in being compatible, verses a bunch that are all conforming to the same standard.
People have been using email since they were five and all modern lives depend on it. If they don't understand federation they will just be confused why they can't see the content and leave. "I didn't understand it and it didn't work" is one of the more commons reasons I've seen on Reddit for failing lemmy
As a younger tech person, I definitely don't get a lot about email. It's old and weird and arcane and half it's features that match newer services seem to be built on top of hacks that are enforced through convention alone that will break if I decide I like to format my titles a little differently. Third party clients work, but the main providers, Gmail outlook use some proprietary api to make sure their own works well while everyone else gets stuck with shitty imap. There's endless little incompatibilities. It all just feels like delerict tower held together with miles of duct tape. Oh and I still haven't found a good answer to why calendars are so tied up with email.
