Google gives me free search, free e-mail, free calendar, free maps, etc. etc. in return for tracking what I do and selling that information to marketers....
I'm ok with this deal, it was made willingly.
You're paying with long-term data for short-term service. Google will one day shut down GMail yet they will still have all of your data to do with as they please. I doubt you considered that when you committed to it and now you cannot undo it.
I will, however, retract at least part of my statement if you tell me that you didn't start using Google services until after the Snowden revelations.
