Earlier quoted context omitted.
It's not appropriate for the Executive branch to make requests to remove content that is political for political reasons. This has a chilling effect[1] and can thus be rightly judged by the populace as being against our shared reckoning on free speech. 1: http://en.wikipedia.org/wiki/Chilling_effect_%28law%29

So USA doesn't negotiate with terrorists but does what they want as long as there's a threat of violence?
