1.6% is insane though. That would be like Google, Apple, or MSFT paying their CEO $4-6 billion a year.

Which is why it's not normal or standard to represent pay that way. The whole reason for it in this context is to address claims that people keep making over and over that they ran out of money to develop the browser because they gave it all to the CEO.

The problem is, the market price for executive leadership doesn't care about that, there is always a floor at the bottom that will make leadership compensation consume much more % of the budget of a smaller org than something the size of Google.

Besides... the real compensation for big-tech executives or for early startup employees isn't a fixed dollar amount, it's the stock options. Let these vest and cool down for 10 years or so, and when you look at them again, they can easily be worth a billion a year. That's how a bunch of "angel investors" in SV got their money, they profited massively off of a good exit event in the past and now invest a chunk of that profit.
