In attempt to end the "pay-to-win" model that has been a problem on Minecraft severs, Mojang thought it best to update their End-User License Agreement, or EULA, to prevent others from hindering Minecraft players' gaming experience and from wrongfully profiting from servers. Sadly, this has led to much confusion.
In response to fans' and server hosts' criticism, Mojang released a statement, legal term free, that explains precisely what is and is not allowed concerning Minecraft servers. Players can be charged to access a server, those who host a server are allowed to accept donations, in-game advertisements and sponsorship opportunities are permitted, in-game items may be sold if they do not affect gameplay with the exception to capes, in-game cash can not be purchased with real-world currency, and those who monetize their servers must provide detailed information to their customers.
The last term was particularly detailed by Mojang. The Minecraft creator specifically expects that those who monetize their servers will state that the purchase isn't associated with Minecraft, specify who the money is going to, provide customers with a purchase history, and supply contact details. Mojang also encouraged server hosters to be sure that what they are selling is legal in their region.
Though the new EULA caused a great misunderstanding, Mojang's desire is that these changes will lead to a better Minecraft experience for all gamers and will end any pay-to-win tactics that have been used on servers.
