There's always another town. And likewise, so many alternatives to Google tech - and all solutions provided by the other 'giants'. Besides, this is an industry driven by technology & innovation. If there isn't a solution or an incumbent is dropping the ball - that's opportunity for geeks like us.
Besides that, why give them the benefit of the doubt anyway?
I have no qualms about singling out Google. Of all the 'giants' this is a company that has the most volume, quality, and relevant information on all of us. They need to be held accountable & scrutinized to the highest degree in the handling of said data. The fact that they are the company most active in their business relations & engagements with the intel sector should be ringing alarm bells.
Like I said, I share your concerns about PRISM but singling out Google seems like losing the forest for a tree when we have abundant evidence that all the US tech giants have been forced to comply with NSA requests.
