You are right when you say that the game is released for free and that complaining about crawling slow releases on a pirate site makes no sense.
However this attitude is starting to get to the point where it's becoming insulting to the patrons who actually fund the game and allow the continuation of developement with their donations. It shows very little appreciation for them and is clearly exploiting the fact that despite this behavior DC still isn't losing too much revenue, while people keep givng money that at this point is not really deserved anymore.
I have donated myself, but now I'm regretting it and I'm certainly not throwing one single more cent into it, no matter what happens.
