You really hit the nail on the head. I can't sign over rights to stuff I don't own. Is there a good chance that this move could blow up in Meta's face, in which the Party B's organize (or are ordered) en masse not sign the license agreement and leave Zuck without the legal ability to steal while also losing marketshare?

I think more and more people like you around the world are realizing not only how corrupt the U.S. is, but that it's power and influence are in a sharp state of decline and perhaps not worth the risk at this point.
