For me, I don't care if Amazon has my shopping preferences. I don't see a list of every item I've ever bought or viewed as particularly sensitive information. If you use Chrome, Google search, Gmail, and maybe have an Android phone, then Google knows everything. Private conversations, every service you have ever used (assuming email is used for login), every thing you've ever searched for, every url you've ever viewed in your browser, basically everything of everything.
