I think a better question is "at what point does anyone get to tell anyone else that their morals must match?"

I'm glad we can agree that Lavabit's action were unlawful... but please don't quote me out of context. "There are rules" was with regard to there being certain rules that need to be followed in order to qualify as a legitimate whistleblower. If you would like to argue that those rules need not be followed then I'll respectfully decline.
