Well, the Azzies have their hands full with a full on war with Amazonia, trying to counter Horizon's fun and games at their expense, and the rest. But really, it boils down to "What does this gain us?" You don't think Aztechnology is on a crusade against dragons, do you? They want Sirrurg and Ghostwalker dead, sure, but what profit is in it for them if they go raising a stink in someplace that is painfully close to Lofwyr's back yard? Moreover, while i'm sure they wouldn't say it in public, the fact is that if all the great dragons decided that they'd had enough of Aztechnology's bull, and decided to declare war, the Azzies would lose. See how much trouble they're having with Sirrurg, and he's just one great dragon.
Oh, and there's the fact that Saeder-Krupp is in control of the Corporate Court committee dealing with problems like that this year. And the Azzies aren't in a position to go flaunting the Court, not when there are nine other corps on the court who would be all too eager to take bites out of the Azzies. If a gag order has been imposed, then Aztechnology would have to stand to gain more than they would lose to risk going against it. And they just don't stand to gain that much from stirring up a panic.
