When making bold claims and assertions, you should cite facts.
Do mozilla not have 1200 employees and top people being paid 1M $ ?
Some top executives and board members are paid 1-3M according to documentation out there, sure. If you compare to other companies where they'd be in charge of as many people at a similar level, this is substantially under what they could demand.
As an employee, they pay us well with great benefits, though I could likely make 2-3x as much at another company (just like the execs). I rather like Mozilla's mission and my work though, and the work-life balance is nice.
