It's going to be a very difficult legal debate at some point in the future. And I bet there are a lot of constitutional lawyers salivating over it :-) If the government can compel you to hand over some information, well that's government. They can also injunct you not to tell people. But, can they compel you to lie, publically ? Can they compel you to not publish such canaries - just in case they want to compel you later on? And frankly, does it matter - is such a canary really just a form of social performance? If I don't want the US government to know something about me, I should stay the hell away from modern life, internet and so forth.
