This post was the final straw for me. I deleted all my accounts on non crucial US based services yesterday when I first saw it. I was already angry with what is going on but it was a shallow meme boycott consisting of only drinking kofola now instead of coca cola. It got serious yesterday. Unfortunately I still need to think about the strategy to quit Google since pretty much everything I do is connected to my Gmail.
If you put random political reason unrelated to the app/service, they can remove it. So be extremely critical about their app and services only, have some high standards in what you expect from such services for the free usage data they "steal" from you.
