If that's the case then it makes a great case to break the DMCA and steal all the content out there.
That sounds terrible in theory but it's one way to put some of these big money systems in check.
What about all the leaked source code in early 2022. It would make perfect sense for the hackers to remove the copyright and put it in Github for karma. That way, the IP of all now belongs to all. I'm quite sure a few won't agree with this method, but that's exactly how bad it is when removing licenses from software for code predictions.
Finally, Git was meant to allow people to host anywhere, so if the worry is about IP theft, one should stop hosting on Github and move it some place else, if they want it fully private.
