As Mojang published a set of rules concerning the equal status of all players of Minecraft, Microsoft would make many more enemies than they have right now by changing much about this policy. Minecraft has a good equipment to maintain a game as big as Minecraft, which is hard for a small Indie studio. That they invest such a gigantic amount of money suggests that they expect a good deal for themselves, but that doesn't necessarily mean that everything will be changed and Microsoft would squeeze Minecraft tot get as much money as possible before leaving it. A part of the Minecraft community will be gone after this deal, but I hope it opens new opporunities for Minecraft.
