if they run a mastodon instance, you’d be federating with them just as much.
are you sure these comments are somehow protected by copyright and they can’t use them? when I post publicly like this I have no expectation of control over use.I’d be very surprised if I could somehow sue a company using this comment to train AIs.
I’d also be surprised if that status changed somehow if the server was then connected to threads?
I can’t find anything like what you’re describing - my instance has a legal notice which is just a disclaimer saying they can’t be held liable, lemmy.world has a fair use and terms of service which are 404s and their privacy policy just says they won’t sell your data (but might use it for internal research) - can you tell me what you mean?
