From both a technical perspective and if the maintainers of these anti-cheat will consider porting or re-writing kernel level anti-cheat to work on linux, is it possible? Do you think that the maintainers of kernel level anti-cheat will be adamant in not doing it, or that the kernel even supports it or will support it. I think that if it ever happens, there will be a influx of people moving to linux, or abandoning their duelboots, and that alot of people will hate that such a thing is available on linux.
If the Kernel is not signed, then it does not matter. The whole point of signed Kernels is to only execute that specific code. Its not pointless. But besides that, even if you don’t like Open Source, nobody said the Anticheat software has to be open source. This is something you implied. I don’t think any of the Anticheat companies would Open Source it anyway, so this was not my suggestion at all.
