And guess what, it can be done just as easily, if not, more easily on a federated instance. You don’t gain at real additional control over your data (and no putting “covered under license X” is about as realistic as those Facebook posts saying “I don’t give anyone access to my posts”).
I’ve said this before and I’ll say it again, realistically the only way to control your data from AI is a DRM type solution which everyone fundamentally hates.
You can use federated SSO. The remote site never sees your credentials but only a token that you’ve been authenticated against your home instance.
That being said, that’s probably the problem, in order to do federation a small degree of trust is required between the two instances. I guess that is already done with activityPub since you’re getting content from remote instances.
