Linux kernel is like 28mil lines of mostly driver and arch code. It’s open enough that you can basically use the code as it is to do what you please… There are limitations of course but the code is out there.

As it is the foundation and kernel ecosystem is seemingly pretty corporate friendly as it prob needs to be.

Are you worried that Linux might be attempted to be recooperated by capitalists somehow? It is a very valuable asset. I’m not sure how they could do it. Maybe they will try and make it more like corporate OSs… Or they will use their legal and sanctioning powers to prevent some people from using it how they would like.
