I hope you're right. That is certainly what I thought before the Snowden revelations. To date I don't think Google has offered sufficient transparency into the process to adequately restore trust. If the NSA (via secret laws or dictums) is preventing this from happening, it is at the expense of Google's reputation.

Further, the recent revelations that the NSA deploys agents as employees of various tech companies (like Google) indicates that Google's internal security processes have been breached and the careful (and likely reasonable) way that cooperation with law enforcement has been crafted may be largely irrelevant.

The above may be wild speculation, and I hope it's incorrect. But considering the Snowden revelations I don't think Google has done enough to make a person or firm that explicitly didn't want the NSA to have access to data its feel comfortable using Google's network and services to store/transmit it.

And, since Google's core business is ads, Google has designed its own systems so that data from any Google service (analytics, dns, gmail, doubleclick) can be used for targeting and behavioral profiling. The scope of it is really quite impressive. Thus I think it's sobering to think about all the data being readily available to the NSA, as Snowden suggests it is.
