Obviously Lemmy, Mastodon, Pixelfed, etc. are federated decentralized equivalent to their centralized counterparts, but what is the counterpart in the fediverse to TikTok? It is a dominant app for millions of people, and as far as I can tell the closest thing is Peertube, but isn’t that more of a YouTube equivalent? Does it not exist because the bandwidth and storage costs are just too great? Or because the algorithmic nature of content selection is inherently anti-fediverse in some way? Clearly many people choose to interact with each other this way, but it seems like a gap in the fediverse and I was wondering why.
I am not trying to be condescending, but I get the feeling you may not be as versed in privacy matters. Those other social media apps require access to huge amounts of information about you and everything you do on your device. Location, location history, health and fitness info, contacts, browsing history, etc. Depending on what company we’re talking about, that info is used to generate detailed targeted profiles to sell to advertising companies, and possibly also to train in-house AI models. Lemmy doesn’t do that because it’s a community driven and hosted platform whose goal is not to sell the information generated by its users.
