Further further further (on fedi instead in this case): I have not had to register on TikTok, Instagram, or a handful of other things, and yet: I can still enjoy the memes, culture, content and other things that bubble up on those platforms, because people will cross-post it anyway. I don't have to wade through trash on TikTok to find something interesting, folks on fedi will usually cross-post only what's worthwhile anyway, and I never have to touch those platforms. I have absolutely zero FOMO from not being on those platforms.
