Non-trustworthy seems a fairly harsh assessment. I've not seen evidence to ever make me think Google isn't trustworthy. I may not be happy with what they do with my data, but it's not like they've somehow broken their promise to me in any way, we have an understanding. I get use of their services, they get information about me.

Why the distinction is important is because if they stated publicly that they weren't gathering a specific type of data (and I felt they weren't legally compelled to lie by a government), I would trust that statement.
