I might be just a single data point, but PRISM is the primary cause of my slow but persistent move away from Google services. Oh, btw, I know many people over here in Europe who never use any Google service other than search out of general mistrust towards the company. Might not help them much, as the search history combined with the IP-address logs of all the G+ buttons is already a pretty encompassing profile, but nonetheless they exist and constitute a non-negligible fraction of the populace over here.
