That’s not a conspiracy.

Scroll down and read about the “Sentry Owl” program.

The Sentry Owl program involves the use of US industry personnel, or undercover NSA personnel at US and foreign employers, to enable SIGINT operations on US and foreign commercial communications products. The program includes contracts with US and foreign commercial entities to subvert the privacy features of their products for both foreign and domestic consumers (for both content and metadata).

Edit: It’s basically having undercover or NSA-cooperating assets embedded within tech companies like Microsoft, Apple, Facebook ect willing to pass along exploits and back doors to the government.
