My understanding is Thunderbird is self funded from donations.

> not unless you find a viable financial model

First reduce expenses by several magnitudes. There is no reason browser should need more than a github project, build QA servers, and 10 paid core developers. But you would need much better codebase for that!!!

As for income, donations come to mind. You can still sell default search, just not to google.

20 years ago browser companies had income from selling their rendering engine for embedded use. They also did consulting...

I mean I do agree – donations plus endowment should work pretty well: https://news.ycombinator.com/item?id=44549144
