The point is software which is free for anyone to inspect and build upon. That's it. It doesn't have to have geopolitical significance, and geopolitical events don't change the overall benefits.
FOSS is inherently political, it stands for softwares both free, per your definition, and free as in people’s freedom. If now any political entity large enough to pull its weight can hijack an entire project, then FOSS is pointless and the people contributing to these projects are just doing some good ol’ work for free, with no benefits for nobody but corporations.
I submit patches to projects operated by companies all the time, and I generally don't care who runs the project (whether it's a company or a hobbyist). I do this only because it benefits me directly. It probably helps other people too, but they're not my problem. The company making money is also not my problem.
I fix a bug or add a feature, which I was going to do anyway. I get that change merged upstream. I can then happily use my Linux distribution's packages (or some other downstream dependency) without wasting monstrous amounts of time replacing those packages with my own locally maintained version.
