even if its open source, other rivals cant use the code because of copyright claims on the nvidia source code, so they would start sueing the shit out of everyone 

This is the case. That said, the information could used as inspiration (to a lesser extent).

the legal system (in america) or in any country really dont care if its "for inspiration," when it comes to violating copyright laws, although nowadays i really dont know what the fuck the legal system will pull out of its ass, all i know is that big corporate companies will ruin ur life because they have 500 (or more) lawyers working under them every day dealing with this sort of shit

I wouldn't be surprised if AMD were looking to cash in on Nvidia's misfortune, albeit with the guidance of their legal team. There's plenty of ways they can inspect Nvidia's technology and continue to develop their own within the constrains of the law. DLSS/LHR are some of the technologies that had source taken.
