>They are dictating what can happen on HN about as much as you are dictating what they can post on their twitter.

Hardly. I never said, "Foone mustn't say X on Twitter", or even "they should not say X on Twitter". The latest post actually contains the phrase "NEVER POST ME ON YOUR SITE EVER AGAIN." I'm not even gonna say that they should not make this demand, I just find it pretty funny that they think anyone is going to respect it.
