*diaspora had something like this, but only in the sense you could easily migrate your identity with a few clicks. Not the same as a SSO, which would be great, imo.

You handed all your data (including your browsing history) to Meta just to take a look around?

They could offer the slickest interface and keep people locked to their friends. That interface can use protocols that make it difficult/impossible for non-Threads instances to play ball (ooh this cool new feature is only available through the Threads app; Oh, my basement.world.ml.xyz can’t read that content). There are many ways to EEE, and I’m sure we haven’t even thought of some ways Threads could use.

I think defederation is our only option to protect what we have.

For example, we cache and reprocess images and videos for you to view, so that the originating server cannot get your IP address, browser name, or time of access.

Yes, isolate me from those scary non-Threads instances daddy
