Mozilla was a highly effective organization when Mozilla Corporation had in the range of 150–200 people (or even less) on payroll. The increase in (paid) headcount has been mainly correlated with:
- the removal of features in the name of smaller surface area (while at the same time adding telemetry and analytics[1])
- other lame fixtures of soulless corporations like cringy/dishonest PR babble
There's also stuff like breaking incoming links to content on mozilla.org; making it steadily harder to contribute; keeping things closed source (whereas before everything was licensed under MPL or some other FOSS license); being willing to cut deals with partners that come with strings attached and NDAs; wasting probably a billion dollars on obviously doomed things like Firefox OS and calling it a "moonshot"; etc.
