If all of these servers do get blacklisted it'll be extremely bad for Microsoft, not Mojang. So I doubt this will actually continue to spread because if all the server who have pay to win features (90% of fucking servers do) this will mean the collapse of MineCraft mutliplayer. Only a few servers will be left and no real chance for newer servers to become big. So I completely doubt this will happen and that Mojang will go trough with it. I doubt Microsoft is down with spending such a huge amount of money into buying the game and for it to simply die.
