Not that it would be necessary in an obvious case like this, but each one of Microsoft/Skype, Google/Youtube, Apple and Facebook could easily have hired the nation's best and brightest one thousand lawyers at $1,000 an hour, full time for 10 years to defend privacy. It would have been well within their means. Yet, each of them chose to back down. Each of them chose to fail their users' trust.
I don't think its due to cowardice. If these organisations cared the slightest bit they would have acted to protect their users. Not in the wildest scenario would the US government have jailed the leaders of Apple, Google or Microsoft. My best guess is they got something in return.
