Not as mistaken as it appears.

The NSA placed key people into companies like Google who had security clearances that specifically forbade them from saying exactly what they were doing to higher ups. They then created systems for extracting data in an automated way based on requests from the NSA. All that executives knew was that they were doing something important for complying with law enforcement requests.

The CEOs of these companies learned about the existence of the back doors from public reporting based on Snowden's revelations. When they first heard, they issued public denials that were, as far as they knew, truthful. Their subsequent actions upon finding out that they were wrong strongly suggest that they wouldn't have approved the programs had they known what was happening.
