Well, if you're so butthurt about people having fun, you're welcome to cover the costs yourself. I can give you the number of downloads my archive got and then you can buy that many copies of Minecraft.
There, everyone wins! People will still enjoy a game and you'll be able to sleep at peace, knowing that Notch will get more money for his vacations.
In any case, your argument is faulty from the start. There's no piracy here since I'm not providing a playable copy of Minecraft in any way. You wanna rage, rage at the guys who made the Minecraft loaders.
