I don't think many would complain about their salaries if what they did actually worked. But Mozilla is being run into the ground before our eyes.
If the availability of people with a non-profit ethos affects competitive pay for non-profits, then that should be taken into a account.
Maybe such a person exists to lead Mozilla. But the primary goal should be to find someone who can turn the organisation around. I haven't seen anything that makes me believe that current management can do it.
