I'm still unclear on the government's ability to compel falsehoods (even the discussions around National Security Letters seem to indicate that they prevent disclosure, but can't require lying), but I don't think I can convince you of that.

When all the hullabaloo around the alleged IPSEC backdoor occurred, it was frustrating to not be able to be as open about it as I wanted (not because of any government/security issues, but because at the time I still worked for the company and we were advised against talking about it).

You are free to assume that even right now as I type this, a shadowy figure in an ill-fitting Brooks Brothers suit is standing over me dictating my responses, and then chastising me for spending my time on HackerNews.
