I think it's more like "I created a tool that used part of Minecraft illegally, violating its license, but released under GPL. Now that you, owner of Minecraft, are releasing this tool, you can't be violating your own license, you must be violating the GPL by having a closed source blob, *that you have the source for*, as part of the codebase. Mojang should release the source code for that blob, and nothing else, to comply.
