Of course they will review it in their spare time. They wouldn’t copy it, but they could certainly learn insights and apply them in their architectures.
No, they won't. Any competitors and any open-source projects will advise their engineers to stay as far away from it as possible.
It's a clean-room engineering situation, if you've even looked at it you're legally contaminated and you're now a liability to the parent company/project's IP. And now those projects have to be hyper-aware of any contributors who might "sneak in" a bit of NVIDIA code that gets the whole project taken down.
