Some of these people even say that Firefox needs to get rid of Google funding immediately to get rid of Google’s influence.

Which is an importnt factor, because Mozilla is currently being kept alive specifcally to lose.

To be fair, those people (and lots others too) watch everyday some millionaires or billionaires just up and throwing money. Under that premise, it "should be as easy" as just convincing a random capitalist with narcissist complex to fund Mozilla. The problem with that is, people's memory on the internet tends to not be retrospeculative, so they don't notice if Mozilla did that they'd be in just about the same position eg.: Reddit was 5 years before 2023.
