There is actually a lot of scaremongering and false information in there. A view from the other side (and compares it to Apple's app store): http://marketingland.com/why-im-glad-google-play-gives-developers-customer-data-33431 As a consumer (and I also frequently by apps), I prefer Google's method. Apple's would be a big headache. Also, when you buy software from Soft Dev Company X, you give details anyway, so there is no difference. So, what's the big deal? Google did document it in their TOS, too.
