For example, 1.9's prerelease. With potionmaking, he ripped off PotionCraft in some ways. Notch even made a manchild of himself when the creator of PotionCraft sent him an email. (Link: http://twitter.com/#!/notch/status/123677995264245760 )
-100 faith in Minecraft.
I think Notch is being a little bit of an ass with his reply, but its just his friendly sense of humour + he wasn't making a manchild of himself at all, it was the mailer who made himself look like a dipshit.
I disagree with some of Notch's ideas, but somewhere I read that any mod you make can be used by Mojang and Notch and basically becomes their property.
But really, I'm surprised that the maker of the mod isn't honoured that Notch used his ideas and mod. I'm really surprised at this. :ohmy.gif: Because I would feel like a king if I made a mod and used it in the game.
