GFDL Smackdown: RMS vs. Beijing Underground

Seems like the Beijing underground authorities have infringed on an image from Wikipedia, which uses the GNU Free Documentation Licence: time to call for RMS?

A Subway map, drawn back and uploaded onto the Wikipedia back in 2004, became some kind of hit icon in the more underground part of the Chinese capital, with the map being used by the Beijing Planning Exhibition Hall (on the 2nd floor exhibits and in the 4th floor 4D movie hall) — and now, by the Beijing Subway.

Obviously, they had no idea what the GFDL meant. Quite frankly, the guy that did the map could sue them — but we’ve never seen a GFDL lawsuit.

Maybe it's time we did....
