Maybe they pull the stuff Nvidia does: write an interface kernel module, then have the driver itself in a library that the module loads. Since the actual driver is never part of the kernel tree...
And courts have decided that it's not enough if you have some contributions to the kernel yourself or are a user to force them to release it, you have to have made significant contributions to force them to release it via the courts.
And Torvalds and the major kernel maintainers all refuse to enforce the GPL, and actively campaign against doing so.
It'd be a long legal discussion to properly answer your question, but luckily OEMs make it easy for us:
On most phones, there are zero external kernel modules loaded. The SoC vendor bakes it all into the ketnel, and the OEM gets the kernel as a blob. Which means all of it is subject to the GPL.
Yep, I had to go sleep (yeah, that dreadful thing!).
But this was my main area of attack. You compiled the drivers directly into the kernel. Making it all GPL. Now, as a strict reading, I have to have the device to make the request. That's not difficult. Ive phones from a lot of US named companies.
I just want the rights enumerated in the GPL as granted to end users. I'm no kernel maintainer. Just a cranky person who wants the GPL enforced as any license.

Yeah, it turns out it’s not that easily enforcable. There are still court cases going on, but the current legal situation seems to be that unless you’ve contributed significant code to the kernel, you have no legal leg to stand on.
Because the OEM is simply saying "yes, we violated the GPL, and infringed the copyright of the developers", but the only ones who could sue against that would be devs that contributed significant amounts of code.
