2.6 million per employee? And infrastructure hosting, especially just for bugtracker / source repo / CI cannot be that expensive.
At that, what are the employees doing? Rust is fantastic and important, but Opus has been pretty done for years, Daala is still DOA, isn't Xiph an independent organization?
I think you made a rather basic maths error, it's 375k per employee.
Firefox still gets an enormous amount of development effort. I think people don't notice because Chrome likely just gets an order of magnitude more.
Xiph is independent but I believe Mozilla employs all the core developers. They're currently working on doing for video codecs what Opus did for audio.
I actually think Firefox is currently seeing more development than Chrome and it's just not as noticeable, because a lot of that development goes into unearthing some of the technical debt that they have (Electrolysis for multi-processor integration, WebExtensions for a proper, stable add-on API), or is an investment into the far-reaching future (Servo).
That being said, I'm not actually that well informed about Chrome's development, so it could also be that I've simply missed some of their development plans...
