My goal, if I were CEO, would be to reduce organizational expenses (and increase other forms of revenue) to the point where the 100s of millions of dollars from Google ($562 million in 2017) was not required for covering the cost of firefox development and spend all those millions on advertising firefox until Google stopped giving it. I can't see where having such a large part of your finances coming from your biggest direct competitor could ever be a good thing, but at least spending it on increasing firefox's market share directly through advertising would have a certain irony associated with it. At least of the Alanis Morisette variety.
