Maybe they could offer that amount in some very LCOL area, I guess? But browser and standards development is highly technical, not something you can easily outsource to some offshore sweatshop. So 50k/year is kind of an insult, and even the purest souls would have a hard time turning down 4-10x that compensation at Apple, Google, and other competitors.

Not to mention, there are a lot of non payroll expenses to account for.
