That's a stretch. It's simpler than that: follow the money. I pay Apple, so I'm the customer. Advertisers and marketers pay Google for access to me, so they're the customer. Just because Apple touts their user numbers doesn't mean they're selling those users. In fact, as a developer, I can't pay Apple to guarantee installs, or even visibility. Apple won't sell me customers. I might like to give Apple money to get leads or users for my apps, but Apple will not do that.
