Add existing Google account without accepting Google Play agreement
I just made an account for that sole purpose of not wanting to give my information, if google wants to take it, I'll happily provide fake information. I knew I shouldnt have bought a smartphone, this was exactly what I wanted to avoid.
"btw, in order to use your phone, and get access to a bunch of things youll never ever want to use, we'll demand all your personal information, access to your phone and microphone (Samsung style) and synchronization of all gallery, but that will be all"
