Cell phone companies will probably hand over such info to any government entity to comply with local laws. I suppose with Google they have it a bit easy, because google links your identity to your phone, email, web search, purchases, maps activity, etc. They don't have to issue 20 different legal requests to each provider, and then combine that data. Other than that I don't see how Google collecting this data is bad (if we're to assume that there is a legitimate reason to do so).
