Bluesky just barely hit a million users is still invite only and is largely in a beta state, and though I'm not on it, everyone I know says it's a zombie platform and they'd rather be on Mastodon for nerd shit or Threads for normie shit. Threads has over 100m users already. The numbers alone make Bluesky not really worth mentioning, and effectively Threads killed it within the first day. Dorsey has also shown a track record of having no idea what he's doing. Probably half of the things people think about with Twitter come from the community. @mentions, rt, the term "tweet", etc. The twitter app was developed by a third party and bought.

As much as Zuckerberg sucks, Meta actually runs like a real company with adults at the helm. Dorsey's already fucking up bluesky not learning anything from his time at twitter and not making moderation a priority. Brands are already embracing Threads over Twitter and Bluesky because they don't want their ads showing up next to porn and nazis.

Oh, and as for GDPR, Meta has already stated they plan for a later launch, and again since it's a company of (sociopathic?) adults, they'll actually get it done, but it's already effectively over.
