ok, armchair lawyering from a non-lawyer.
The one major rule is that you must not distribute anything we've made unless we specifically agree to it. By "distribute anything we've made" what we mean is:
And so that we are crystal clear, "the Game" or "what we have made" includes, but is not limited to, the client or the server software for our Game and includes Minecraft Pocket Edition on all platforms. It also includes updates, patches, downloadable content, add-ons, or modified versions of a Game, part of those things, or anything else we've made. Otherwise we are quite relaxed about what you do - in fact we really encourage you to do cool stuff - but just don't do those things that we say you can't.
OK, so they say that they are quite relaxed and permissive. Just don't do what they say you cannot do.
So, right away, this EULA differs from most in that this EULA is explicitly granting permission unless it says you cannot.
That is a game changer for a lot of assumptions.
There are two potential issues for people selling schematics of content:
make commercial use of anything we've made;
try to make money from anything we've made;
Strictly speaking, these could be read as prohibiting commercial servers, yet they have clearly stated that you can, with certain restrictions. So these are not 100% absolute.
If I wanted to make money from selling a minecraft picture, would that be making money from something that they made? Iffy. Unclear.
Selling a detailed, close-up view of a block? Sure, that's a direct violation of their artwork copyright.
Selling a picture that is a big landscape, that has a massive amount of work and effort put into it? The USA has a copyright exception for "Fair Use"; would this qualify? I don't know.
Selling a file that describes a set of blocks and placement, used to re-create that landscape?
Well, now you are not selling anything of Mojang's. You cannot turn that file describing block placements into art without having Mojang's game, so you've paid Mojang (and their art fee), load it up, and now you can see the landscape you purchased.
And this is the key point.
You are not selling a picture of mojang's art work.
You are selling a file describing how to place blocks, that will be used by a mod to set up the blocks so you can view the art in 3-d.
