What about for creating and keeping up a global surveillance-capitalism system where billions of people are tracked, profiles, stripped of their privacy and manipulated, thus disrupting democracy and civic society?
You are ignoring that the government can and does request data from the companies. You may say 'who cares about the adidas I bought', but it doesn't stop there... google knows where you are (location services in android...), who you contact, what sites you are registered to (contatct synced / gmail), in addition of what your interests are(are you gay? involved in casual sex? voting republican or democrat? Planning a protest?).
This level of data collection is wrong regardless of who does it: if a company has this data the government can get it too by definition, after thr data is there it's just a slippery slope.
"(funny how privacy advocates are more upset about Amazon knowing your secrets than the government, who have an actual incentive to use it against you)"
Actually going to disagree with this one. AFAIK, the government has not used their collected information against me at any point in my life as far as I can tell. However, these tech companies are using it literally every day to try and manipulate my decision making.
