This was a "they're out to get us" kind of conspiracy.

The NSA sought to expand its own power in secret though quasi-legal means with the help of a few powerful men in government and a lot of scared people in corporations. The conspiracy used leverage to force cooperation by companies. You don't have to be evil in order to do evil by cooperating with a conspiracy, even (especially!) one run by the government.

All that is required for evil to triumph is that good men - or good companies - do nothing.

If for something to be "a conspiracy" you require that EVERYBODY who helps the effort be consciously furthering the actual goals of the conspiracy, you've defined conspiracy in such a way that it is unlikely one could ever exist. In any actual plausible conspiracy there will always be unwitting dupes. There will always be people who've managed to convince themselves that they personally are doing good or that the organization is good even if the effects it produces don't turn out that way.
