Did you include the fees Google has to pay to Apple, which they don't have to pay to themselves for Android? The whole thing is also not binary. It is fine that Google has ads on multiple platforms targeting multiple demographics and markets. It would be problematic if 100% of the ad activity was on platforms controlled by others. In other words, having some (or many) of your eggs in someone else's basket is okay. Having all of your eggs in their baskets leaves you very vulnerable. There are other big Google benefits to Android. It keeps people using Google services, including when they use other platforms. That makes the other platforms have to play nice with Google, and restricts the amount they can take away from Google. An iOS user who uses Apple for everything (mail, calendar, etc) is far harder for Google to monetise.
