So as some of you may have been following there has been a big upset in the past week about Pay-To-Win servers and Mojang has hence resovled to do something about it. The result has been a backlash on any server that operates as a business or turns a profit in any way other then "pure" donations, anything that might have some conflict with the End User Licence Agreement (EULA). In essence Mojang has announced that they are against servers being used as anything but amateur "fun" side hobbys and will be changing their EULA to be further in tune with this, but don't take my word for it and let's have a look at the evidence and Mojang's statements:
Firstly the EULA;
Their "One Major Rule" is the only thing in question here, that states;
• make commercial use of anything we‘ve made;
• try to make money from anything we‘ve made;
It also includes modified versions of a Game, part of it or anything else we‘ve made.
My initial interpretation of this is that this would include any items and/or abilities already located within the game and in addition any modifications to the client itself. Also any of these included within a server that runs the Minecraft client. MCPVP has taken action to avoid this clause with the retirement of HG kits that's sole benefits were items already included in the game (chemist only gaining potions etc.). However in a statement by a Mojang Employee Erik Broes this includes plugins as well.
"doesn't matter at all, based on plugins or not, you cannot make money with Minecraft without our permission :)"
While I disagree that plugins that offer entirely new features or effects that aren't just modified existing content are included in this, in Mojangs perspective they are. Legally this would mean the sales of anything into a minecraft client is in breach of the EULA. What this means for MCPVP is that under this perspective all ranks and permanent purchases are in fact in breach. Previously this hasn't been a problem but in the past week this has been raised and action has been promised. A change of the EULA has been announced to include a way for servers to cover running costs, most likely (not confirmed but leaked) restricting payments to be Pay For Entry or by Donations.
"donations are no problem, but only in that purest sense, you get NOTHING back for a donation"
While I doubt that Mojang would be stupid enough to follow through with attempting to shut down those servers in violiation (95% of servers at least) despite their threats to do so, it is something we all should be aware of and is really interesting to follow.
