Man 9/11 was pretty bad... But it was bound to happen eventually. I think everyone overreacted.
Just because something could have happened, doesn't mean it should have. I've seen a number of people in here try to justify downloading from the link, then posting videos of them using it... Though you can still tell with each post how bad they feel for doing it. If I were you I would enjoy it in silence, instead of letting the world know that you won't give two independent developers 5 dollars (or wait one week) for something they dedicated a large portion of their time to.
Dude, Margen67's signature literally says "Piracy is right." He's either a troll or an entitled brat, in which case he probably doesn't understand that people who work deserve money and will attempt to incentivise people to give them money.
I honestly don't blame people for downloading the build; I probably would have too if I weren't donating. But still, if you can't wait a week for something you're probably not going to get too far in life.
