They make more money with much much more primitive “targeting” because they are sitting on top their own platform with no competition. If someone wants to display their ad on the Apple platform, they pay apple.

I don’t mind being targeted by searching for “mobile game” in the app store and it displays a mobile game ad, and maybe even used up that I’m a male in his 20s. That just can’t be compared in good faith to what google or facebook does.
