Thanks, interesting. (Although I can't help but mention: having had a bunch of classes teaching you how to properly distribute information and knowledge using a screen and powerpoint-style slides, this one sure looks like a total abomination to me - and looks can be deceiving unfortunately, they really don't add to the credibility here)
Yes, I was thanks for finding that.
And exactly no information on how Microsoft cooperated or caved. For all you know, the slide might just be indicating the NSA implemented Microsoft-specific parsers before others. Or that they tapped MS fibre or datacenters.
This particular part of the surveillance is what really hurts the bottom line.
