It's nice that you see it that way, I could be wrong, but I *think* the majority of scene developers do not agree with you.
It's not a question of what amount is donated or what the salary of your day job is. The line of thought here is that someone else is making money off of work that you and many others did for free, and gave away for people to use. Currently it is my opinion that this is wrong on principle, it doesn't matter how much they make, or that they're claiming that it's just for support.
Still, it's interesting to me that the only developer who's spoken up in this topic is you, and you have nothing against iATKOS receiving donations.
Not to worry... they'll be driven out of business very soon by an army of Apple lawyers.
