Two possible outcomes of Mozilla losing Google's funding: Maybe Firefox evaporates away to nothing, 0% market share, and now Google loses the fig-leaf covering their browser monopoly. Or maybe Mozilla loses their ineffectual but greedy leadership, allowing people who believe in the mission to step into those roles.

I think Google prefers the status quo to either of those scenarios. They prefer it to the tune of hundreds of millions of dollars a year, for that is how much they pay to perpetuate it.
