At the very least it produced some dissonance between democratic establishment and their support base. Bill and Hilary continue to tour the country and I attended their road show in Seattle. Crowed cheered at every statement until they got to, and I quote, “Snowden is a traitor”, which produced very confused and subdued cheer. It was very fun to watch.
This is exactly what PRISM was, not taking data from servers, but tapping into the data networks between them and siphoning off whatever the NSA wanted. And it just so happens that to mirror a fiber optic line you use a crystal prism.
It actually changed a lot how some companies handle government requests for data. Apple for example, completely switched their strategy because they wanted to be seen as protective of customer data. They realized that data requests would eventually leak so they avoid storing identifiable data on the servers. They saw privacy as a competitive advantage.
