@duco @AmyZenunim lol, my point is that you're being naive for thinking that's what'll happen.
Firstly, to address your claim that """If you don't interact with people from Threads nothing is shared with them, that isn't public.""" As long as anyone on Threads follow you, they have access to all your posts except DMs. If you message someone there, they can also access those DMs. There's a lot of data to gather there. Not just that, but if you personally block Threads but literally anyone who's followed by someone on Threads boosts your post, they get access to it, even if you require authentication for API access.
This is part of why instances need to block Threads. To protect their users from a company who have historically over-collected data and mishandled that data.
Anyway, look up Embrace, Extend, Extinguish. Historically, what's happened is that big corporations have embraced open standards, extended them, and made it basically impossible to run on your own. XMPP and email are both great examples of that. Corporations want money. There's literally no way Facebook would've followed the ActivityPub standard if they didn't think it would benefit them in some way.
