After a period of branches and patchsets, full national hard forks are going to become de rigeur, and linux-derived OSes across the world are going to bloom necessarily, as we no longer have the kind of ambient trust required to collaborate across borders.
Look forward to Euro-linux, Sino-BSD, and I guess probably some sort of GCC-area build as well.
Patches will be accepted across national boundaries with only the highest scrutiny, which itself will likely be provided by nationalized AI platforms.
Gods I hate this era
