However, what right does Mojang have to dictate this?
Ignoring the legal aspect, this strikes me as a dick move. I'm certainly not interested in pay-to-win minecraft servers, but if people want to use them with their purchased copies of the game, they should be able to.
Given the "what right does Mojang have?" question, though, the answer is that assuming the EULA for the server code is enforceable, copyright is the right they have.
I could buy a trademark infringement argument, perhaps, but copyright doesn't seem to really make sense.
Obviously, it only matters if someone notices the noncompliance and lack of the license. For example if Mojang actually sues.
This is the kind of priority fail I'd expect from EA or some other massive publisher, not an indie rockstar like Mojang.
