I wonder how Facebook is going to deal with the inherent privacy flaws of federated social networks. Nobody cares about things like the GDPR or the CCPA for medium social media servers like lemmy.world or Mastodon.social, but when it comes to giants like Facebook and Tumblr things may very well become problematic. No way Facebook is going to sign a data processing agreement with a couple of thousand Fediverse servers.
Pretty cool that the Fediverse is good enough for Facebook to continue investing into it. With Threads, WordPress, and Flipboard, we may very well see more companies cross-integrate through ActivityPub in the future. I don’t think Bluesky’s federation model will take off, despite it being a lot better on technical level for large services than ActivityPub is.
