Notch is trying to own the word "scrolls" in all media. This has implications not just for that single company, but every gaming company that ever wants to use the word "scrolls".
To me, that's scummy behaviour. People should not be able to trademark single words across all forms of media. It does not matter if they made minecraft or not, they do not deserve to own the word 'scrolls'. It's an english word, it belongs to all of us.
