Fair--depending what "most" is weighted by, I may have overstated, and a Google employee who happens to get assigned to work on Chrome stuff is certainly making no personal sacrifice.

I meant independent volunteers or people working for free-software-focused companies (which I believe usually offer well below FAANG-level compensation, especially at the high end, though still enough to live quite well). Excluding hardware vendors porting Linux to their own products, I believe the core kernel developers tend to fall in to that last category. I have no specific knowledge of their individual compensation, but the technical leads responsible for closed-source projects of similar scope make incredible amounts of money.
