Quote fromI think it is horrible that people pirate this game. The people who play it, and put it on the pirating sites obviously must know enough about it to see that in order for it to expand and improve, Notch relies on the profit made from selling copies and donations - he doesn't even ask a ridiculous amount for it! If you like Minecraft, show respect and buy it!
Pirating this game is just plain wrong, as it isn't made by a wealthy and huge company, but by an independent newly started one.
Some people just have no morality.
Judge more why don't you?
Pirating the game has nearly no adverse effect on Notch. He doesn't lose a sale, he doesn't get physically harmed in any way, and if anything, it helps him because of advertisement. Many people would never buy the game without a chance to pirate it first, so one could also say that pirating is actually directly bringing him sales, in combination with the advertising.
I haven't pirated it but I'm not going to condemn those who do, or act as if I am better than everyone else. Mainly because I don't listen to, and don't view the morals people lay out for me as absolute, and automatically condemn everyone who disagrees with me without thought or consideration.
