Well, technically "our" unit icons fall under their copyright, anyway.

And they've always disapproved of players accessing the game files. To them, we are trying to decompile and/or reverse-engineer their copyrighted/patented/etc. software, a big legal no-no for just about any software. Taking legal action would be expensive and terrible PR, so they just stick to controlling their own little neck of the Internet by banning those who spread game-file-only information on their forums and making it difficult to find your way here from there. It could be worse - they probably have the right and ability to ban/block users' game accounts, but I've never heard of them using it.
