> How else do you explain how they are willing to pay a competitor $14 billion+ a year?
Obvious that they have more than >14B+ value extracted out of their competitor's ecosystem per year? I am not sure if you are aware of this or not but when Apple screwed FB with all the anti-tracking changes, there was one notable exception - the browser. Guess who benefited the most? All the ad dollars, which used to be spent on FB and other user-targeting based ad products, are now being diverted to search ads. Just read Google's earnings report - YT revenue declined while Search Ads revenue shot up.
> Who do you think business would rather target iPhone users or Android users?
Think 2-3 steps ahead. How do businesses target users? Via ads in a significant way. If they cannot target iPhone users anymore based on user data, what do you think they will use instead? The next best thing they know - Search Ads. Btw this is why you will Apple and Amazon's ad revenue surging as well.
