Not specifically about Firefox but: if nonprofits can’t pay for talent then you get what you pay for, crappy talent for important positions. That said many people have your mindset so that puts all nonprofits at a disadvantage against any for-profit initiative as far as getting talent goes. You shouldn’t need to martyr yourself to do something good.

Why would I volunteer for an organization that pays its CEO something like 70x the average American salary?
It doesn't operate itself like a nonprofit. I don't want to put my free time into a project that exists to pay for someone's private villas.
