The industry, foreign and abroad are full of egotistical infants.
Itano was simply lashing out at Frontier for one reason: he was not part of it. And so, he's throwing a temper tantrum to anyone willing to give him attention. Like a child.
Itano needs to get over himself. Yes, he does bring up a few points, but as Eugimon points out, he does contradict himself. Thus reiterating my initial commentary about the man. Boy. Child. Infant.
Personally, I liked Macross Frontier. It wasn't the best of Macross, but it wasn't the worst either. As a whole, it was lacking, but entertaining. It felt Hollywood to me, in the sense where it was a lot of flash and not enough substance.
And yes, I am a fan of some of Itano's work, but he is still an infant.
