The point is that for the Firefox to gain more foothold Mozilla first needs to break the dependency on Google's money. And this won't happen without deep restructuring of the Mozilla corp, starting from the top and shedding all the blubber all the way down. The chances of that happening are next to zero. You can label that as "defeatist non-arguments" all you want, but that's a very unfortunate reality. Saying this as a die-hard Firefox user of almost 20 years.
