Yes. And other than Firefox, Mozilla was spending money in two ways. First creating new paid products in an attempt to have revenue in case the Google money ever went away. None of them were successful enough to meet this goal, but it was a good goal. Secondly, they spent their charity donations on activism work. The way they are structured they legally could not spend that money on Firefox. They would need to restructure as a non-profit corporation (not tax deductible charity) to accept donations to spend on Firefox, like their Thunderbird subsidiary. I hope they do so now, and at least attempt to support Firefox on donations.
The truth is that browsers are a very complicated, very quickly moving, and very security sensitive piece of software. They spent all that money on Firefox rather than saving it because if they didn't Firefox would have fallen behind Chrome and Safari and it wouldn't be worth using today.
I would put that heavily on the “excuse not reason” category. The public doesn’t understand this nuance and I hope you’re right about next steps.
It makes no good goddamned sense that money that was given in order to be featured in a web browser cannot be spent primarily on that web browser, and can only be spent on anything except that web browser.
