 :::""In cases like this the Wikipedia Foundation paid legal talent contacts them and they usually eventually see the virtue of complying with our copyright license as it is the only thing that gives them the right to distribute significant amounts of Wikipedia content in the first place.""  Not to be too rude, but this is completely wrong.  The Wikimedia foundation does not own copyright on any articles so the can not enforce the GFDL.  It is contributors like me who write and send such letters; to help, see Wikipedia:Mirrors and forks.  Also, websites rarely comply with such requests, rather than usually.  -  "
