Jokes aside this will always be the case when business
interests clash.
I'd
also assume Encyclopedia Britannica tells it's
professional editors not
to
improve articles on Wikipedia since it competes with
their product.
Britannica actually uses my picture obviously taken from Commons
http://www.britannica.com/EBchecked/topic/435388/Oum-er-Rbia-River
with a proper credit, but they never informed me (not that they should). I
believe at the time I uploaded it this was the only free picture of the
river. Now I have a nice addition to my publication list.
