Elephant in the room is of course the amount of data that is sent to the u.s. from phones in the rest of the world. Hardly a surprise that China is getting in on the action too.
I am also a little curious about what the manufacturer (or by extension the PRC government) could do with data from a phone in the US? I actually prefer my backdoors to open to Beijing... they aren't likely to share, and they aren't in a position to do anything to me (I would obviously feel differently if I was a Chinese citizen).
When the same is sent to China, it's outrage?
Ditto with auto-updates.
I'd be glad if I could control much more of my data exposure. But business.
