I have zero sympathy for people who make a crappy game complaining that nobody will buy their crappy game, blaming it on piracy. Piracy is a factor of course, but AAA pc and console games make a fortune even though they are often the most pirated.
When he released a "crack" of the game that's perfectly functional, he skewed his own results. It's like leaving your car with the doors unlocked and a sign that says "doors unlocked, keys inside" in a bad area. Of course somebody is going to steal it, you gave it away.
He casually says "they wouldn't have missed that 8 dollars" as if everybody in the gaming world can just throw down 8 bucks on a homebrew game every time one pops up. Many can, of course, but just as many might be poor, underage, or live in third world nations where that 8 dollars is a buttload of money.
I want developers to succeed, but blaming piracy is a scape goat. Doom was probably the most pirated game of it's time, it was also the best selling game of it's time. If you make a good game people will pay for it.... it's as simple as that.
