So ... Threads.
Facebook is coming into this interaction with a long history behind it. It's not a random group or small community with a special interest. It's a behemoth in the explicit business of turning human interactions into money.
They're starting with a negative trust balance. We have no belief that they would ever enter into any arrangement that they were not the sole beneficiary of.
We believe, even if we do not understand or see the mechanisms or tactics, that they intend to exploit us, our users, and our communities.
We will not be entering into any federation with them via their Threads platform or any future services.
If they do nothing but positive things in the network for a few years, they might just start creeping up to the point of "zero trust" we'd offer to any new instance and maybe then we'll be open to discussion.
If you really want to see Threads posts, maybe get a second account somewhere that is federating and try it? You're allowed! There's no limit!
