>Mozilla has not been able to act aggressively as a commercial player. Just one example: KaiOSTech ...

I am just speculating here, but would this involve significant compromise on Mozilla's core values - specifically privacy? For example one of their investors and partners is Reliance Jio (the reason why KaiOS is the second most popular mobile OS in India) who brag about monetizing the data of their subscribers as a fundamental business model and strategy. The reason i was excited about FirefoxOS was that i was hoping that they would do the same for mobile operating systems as they did for the World Wide Web. Personally, i trust KaiOS devices even less than Android in that regard.

AFAIK privacy had nothing to do with it. Mozilla did not want to keep investing, it lost hope in getting traction and had no other mobile-to-scale play, so it pulled back to focus on desktop. Confirmed in private comms from multiple execs.
