"Apple represents a strong alternative to people creeped out"
The question is "how long"? Even Miicrosoft for a while "scroogled" Google, just to adopt the same exact approach as soon as Nadella took the helm - as consumer OS sales revenues were probably declining, especially since very few people saw a reason to upgrade to Windows 8, and OEM sales were impacted by slow PC sales.
Right now Facebook made very unpopular the data slurping, and Google and YouTube are just behind in behavioural targeting, so Apple has an easy hand.
But if in some years the current outrage fades out, without real legislative changes and checks, and if Apple revenues decrease due to longer upgrade cycles (as we saw already in the PC market), who is ready to bet Apple stakeholders won't ask to monetize customers' data too? Who knows, Cook might really think Apple can avoid selling data on pure ethical reasons, but he can be replaced as well.
