Sure, and I can totally understand why he would be upset about that, as he said in his email to mntmn, he's been making hardware for Amigas in a time when almost nobody else has. Seeing that investment now being threatened by homebrew hardware must be very difficult.
That's why I think it's a shame that he doesn't approach projects as a friendly partner who can handle all the boring parts of getting a product in the hands of users. He'd still be getting some money from it, and would be everyone's hero.
