No competitive disadvantage
> the NSA rifling through service providers' servers was not seen as exacerbating these concerns.
The reason nobody at the top is concerned is because the NSA are shafting every company, equally. It's not as if there is one particular company that is under greater surveillance than any other - the NSA is being (laudably) non-discriminatory over who's privacy they violate. Therefore there's no reason for customers to single out any one company as having more or less of their rights infringed. It doesn't matter where you go, you'll still be spied on.
Of if the NSA is targeting particular organisations, they've done a better job of keeping that fact under wraps.
