I think that was also the common approach to paranoia about your privacy pre-Snowden. But he kind of ended that discussion for many, although denial or ignorance is probably better for your soul indeed.
He didn't end the discussion, he presented evidence. When you receive updated evidence you should update your beliefs.
He presented good evidence that big corporations are co-operating with the NSA, or something, but he didn't present any evidence at all that regular Linux distros are monitoring all your keystrokes. As far as I know.
To just wildly speculate about mass surveillance without evidence is just baseless conspiracy theories, you really have nothing to worry about. Hope that helps.
