This is all straw man PR at this point.

If companies were REALLY concerned with this, there would have been stories years before Snowden came forward with titles such as "Microsoft Demands US Government Allow More Transparency on Security Concerns with 'Potential' Constitutional Implications"

Instead the cat is out of the bag and now all of a sudden these companies want to talk about how the gag order is something they all hate.

Better to ask forgiveness, I guess.
