Ok, it seems we're both right in a sense. They do release obfuscation maps to help modders. However, they are adamant that this does not make Minecraft open source. I'd also be a bit surprised if they include in those maps the source of DRM/online activation components (relevant to the original topic).

Also, I looked at one of these things, and it's just class names, method names, and source line/column numbers. There's no comments, no variable or parameter names, no original source lines, and no hints about what optimizations or inline obfuscations were done.
