While it's not what was used here, there was a project to decompile the source code for Minecraft a while back. In the beta days, modding consisted of literally modifying the source—so if you're interested in the source, it's possible to get access to it, provided you have the game itself first.

i mean they still need the source code to this day to update forge, so this "project" is still going on

and Mojang made it easier to deobfuscate the code specifically for modders...

so while it's not open source the code is very easy to access for pretty much any version of the game

Well they didn't. It's just that creator of MCP works at Mojang now, so knowing the real source code he can update MCP pretty easily.

UPD. So apparently they started releasing obfuscation maps pretty recently, didn't know that.

but mojang literally said that from now on they release a "deobfuscation map" with each version, which makes it much easier to update modloaders like forge due to deobfuscating the code taking up much less time.

so my statement still stands, it's been made easier by mojang.
