Right. And how would you feel if Mojang started shutting down certain mods for BS reasons and basically just said 'We don't want you to play the game THAT way. It uses our code so that's that."
Would every Minecraft player just say 'OK.' and go back to Vanilla?
As the company who made the game, they have a absolute right to tell you how the game should be played, after all they made it, they have the source code, they can move shit around so much that could make everysingle mod out there useless. Of course has bluehorazon already say, they wont do something like that since mods are the number 1 attractive of the game and the reason almost 22million of people around the world bought the game.
In normal situations, if you dont like the way a game is, you absolutely complain about it in a forum that has nothing to do with the game (Although related in a obscure way) until the creators do something about it............... oh wait? No you dont! you simply dont buy the game and look for something else you would want to play.
Think of every mod of minecraft as a game and the above analogy is complete.
Save this in you harddrive saul, you dont have absolutely no right whatsoever to tell a developer how he should or should not develop his/her mod or what stance to take when something altering his work appears, you are just the user/final user the only real thing you get to decide about the mod is if you decide to download it or not.
