Bad comparison, but I understand your point.

I would be interested in knowing how much of what Mozilla does brings money. Isn't it almost exclusively the Google contract with Firefox?
As a non-profit, Mozilla does not seem to be succeeding with Firefox. Mozilla does a lot of other things (I think?) but I can't name one off the top of my head. Is Google paying for all of that, or are the non-Firefox projects succeeding? Like would they survive if Firefox was branched off of Mozilla?
And then would enough people ever contribute to Firefox if it stopped getting life support from Google? Not clear either.
It's a difficult situation: I use Firefox but I regularly have to visit a website on Chrom(ium) because it only works there. It doesn't sound right that Google owns the web and Firefox runs behind, but if Chrome was split from Google, would it be profitable?
