I think you're asking the wrong question. It's about the company's motivation.
Google makes money from your data, and by showing you ads.
Amazon makes money by creating services and devices that sell you products.
Apple makes money just by selling you services and devices.
Looked at this way, I certainly trust Apple more than Google or Amazon, and this is borne out by Apple's recent "A message from Tim Cook". http://www.apple.com/privacy/
Yes, this. My gripe is not privacy-related. It's that we've built an entire society that puts things to spend money on in my face, and studies me to better learn how to do that. Google and Amazon are both problematic in this regard.
It takes most people aback when I say that Facebook is probably a much richer intelligence agency than the NSA. And people offer that information to them. Data is far too valuable and it creates the wrong incentives throughout life.
