The problem is that the browser market is not actually a direct market for browsers. People don't buy browsers. They buy OSes, computers, phones, tablets, cars, fridges and other devices that happen to have browsers in them. So the incentives are very skewed, the available resources too. Google will always out-compete Firefox in a relatively short time on whatever metric Mozilla comes up with. (If Google wants to of course. That's why Apple is doing all this privacy marketing thing and providing subpar but privacy-aware products.) Ideally the browser and the web ought to be unbundled. People who pay for the Internet access should have a voice in where the Web goes. The ISPs should transfer some money to browser vendors. Sounds crazy? Yes, but that would at least provide different market forces. (And maybe browser vendors should be prohibited from accepting any other sources of revenue. Okay, but what about pull requests? Yeah, good question, this was never an easy problem.)
