I don't understand Mozilla. How did the go from a lightweight Mozilla Browser alternative to a company that spends $450m annually and dedicates $43m just for future endeavors? Why couldn't they just focus on making the best browser possible with a small dedicated team?
Nowadays, a small team is simply not enough to develop a browser and keep up with the competition. Unless you fork Chrome, of course.
They made $450m in revenue in 2018. What fraction of that is actually needed to keep a productive browser team afloat?
Assuming that Chrome team have thousands of engineers, designers and PMs (which is a pretty reasonable number as a modern browser is comparable to OS), I expect them to spend more than a billion each year. Mozilla is really in short of resources.
Other browsers do just fine with significantly fewer engineers.
