This issue affects EddyTheOliviera and Eppy quite a bit, for they do YouTube videos of Minecraft. Oddly, they have not posted here yet.
I heard from MirceaKitsune in the Minetest forums that Nintendo is one of the strictest companies on the planet in terms of copyright laws. If they can allow Zelda Classic to exist, then Microsoft can allow Minetest and Freeminer to exist (speaking of Minetest, a few Minecraft players switched to it.)
