Is _Apple_ known for being "I-want-all-your-data"? Historically, they don't seem to have been terribly interested, certainly not as compared to the web-centric companies.

That's really a lazy mischaracterization of Apple. They've never been especially interested in your personal data. The only service they have where they maintain any sizeable, persistent consumer information seems to be the iTunes store, and as far as I can tell, they've never tried to monetize/share that information with anyone. I'm more curious why you would think of Apple this way - "I-want-all-your-data"? Maybe Apple "you-didn't-really-buy-your-hardware", but "I-want-all-your-data"?

If anything, I would liken Apple to a jealous and abusive boyfriend - they'll beat and abuse their customers with sometimes arbitrary controls over what they can do with their hardware, but God help you if you try to do the same to their customers. Whether you're a third-party developer, an accessory manufacturer, or anyone with a relationship with those customers, Apple will come down on you HARD if they think that you're harming their platform or exploiting their customers. From that point of view, Apple's action here - trying to interfere with RS' sale of Apple customers' personal data - is typical of Apple.
