I don't know who has or has not used that approach, but if you're going to say "Chrome is popular because it did these things" I'm going to wonder why Mozilla didn't do those things. I remember the first time I downloaded Chrome was because I got some item in Runescape for doing that. Why didn't Mozilla do that?

Mozilla has hundreds of millions of dollars at minimum, very likely billions. It's absurd that they're failing so miserably, and it's obscene that their CEO has taken increasingly large 8 figure bonuses while the company has floundered under her leadership.
