Dvorak's article is a regurgitation of previous HN discussions on this topic. I have said in the previous HN post and I will say it again here: don't pile on Microsoft alone. These spying policies make every US-based services company untrustworthy to whomever privacy is important.

Yea, remember that PRISM is designed to target foreign communications, so if you are an American, you might be actually safer.
The only proper answer to that is to stop using American products (at least until the US government can prove with extreme oversight from Europeans and Latin Americans and others, that they aren't abusing their spying power anymore).
