They have an advertising platform already, right?

Apple has been around for a while, they I wonder if the company has some institutional 'survival instinct' that's identified growing the ad platform become too much as long-term unhealthy. It is a corrupting influence that makes the consumer into the enemy, after all.

They've also managed to become incredibly huge while somehow mostly dodging the eye of regulatory bodies. Privacy could mess with that track record and I'm sure they are aware of that fact.
