‶Firefox usage is down 85% despite Mozilla's top exec pay going up 400%″ -- https://calpaterson.com/mozilla.html
Yes, the kind of leaders that forget the core of what they are doing and that make shady deals and decisions like this. "World-class leaders" are sharks and have no place in a company for common good.
You're equating greed and competence. It's an oddly common mistake.
NGOs and benevolent societies are attractive on the basis of their values.
If monetary compensation were correlatory with quality products, we clearly wouldn't be in this position with Firefox: Mozilla's current leader is clearly world-class by your own definition (where world-class==well remunerated), and is yet demonstrably failing the company on every possible metric.

I'd rather have people that care about the cause in charge of these NGOs.
