The change in the TOS was nearly a year before G+ was rolled out and has others below you have pointed out they are making android into another proprietary OS and by ramming G+ down your throat with damned near every service the profile they can build on you is Stasi levels of scary. If you use Gmail and YouTube and give up and log in to YouTube they know what kind of shows you like, what kind of music you listen to, YouTube was very separate from Gmail and Google for precisely that reason and Google USED to talk about how well they protect their users while using that as an example.
So anybody who claims someone who no longer trusts Google is an Astroturfer? Sorry but they need to stop sucking Gdick and look at what the company has been doing the last couple of years. If I said a company knows where you are, when you are home, what music and shows you like, who your friends are, where they live, that sounds like something out of 1984, right? That is simply what a Google services user with an Android phone has already divulged without even knowing it.
There are several articles out there showing how much intel Google has on their users, wouldn't want to be called an astroturfer though so I'm sure you can look it up, might want to use Duck DuckGo to do that search, just FYI.
