I have one thing to say, and for those that have sensitive eyes and have actual emotions: Please look away now.
FUCK WIKIPEDIA!
Alright, so that wasn't very mature - was it ? The truth is that they won't bother with bitcoin, and they will use any reason they can come up with. The only way they will start accepting Bitcoins is when it has become relatively mainstream. The problem here is that Wikimedia has grown too big and has forgotten its roots. I will also not hesitate to use it, without offering a dime in return. I have already offered bitcoins, they rejected it.
