People are saying it isn't affected by the first amendment, but it seems pretty gray to me: Facebook is doing this because they need to sell a good story to congress. If they don't have that story, congress seems likely to bring the hammer down on them. Obviously the threat is assumed. But can congress explicitly threaten a company? Is this all congress needs to do to run around the first amendment in the 21st century - threaten internet companies to do it for them?
