I must be in the minority here, but I'm no more concerned now than before reading this, and I'm still not super concerned if it works the way I think it does. It doesn't answer the main question of HOW MANY USERS are being watched like this.

We already knew from Prism that Microsoft is providing data to the NSA, and we already knew that it included real time video, emails, messages, etc. So this is more of a behind-the-scenes of how it's done, but if you stopped to consider before what Prism meant then it sort of implies everything here.

BUT, I still don't know whether this tapping of Skype calls, providing of decrypted messages, etc, applies only to a few specific people who the government has warrants for, or for all of Microsoft's users. I still think it's the former based on that Prism slide that said it cost $10M/yr, which is clearly not enough to handle ALL of Microsoft's and Google's and Apple's data.

If anything, I applaud Prism in that it's just a more efficient way of doing what the NSA is already cleared to do.

I'm MORE concerned about the warrantless Verizon metadata tracking for millions of subscribers, Clapper's lies before Congress about said data, the DoJ classifying the FISC's rulings that something or other is unconstitutional, the inability of companies to discuss NSLs.

But this release is just clarification on what we already knew, and we still don't know whether PRISM is oh-my-god-the-government-is-tapped-into-everything or just a convenient front-end on the government's warrant-obtained data (which is a good thing, AFAICT).
