Wikipedia itself does not support advertising through or on the Wikipedia web site or any of its articles. I do wonder, how do they then receive the ad revenues from something they don't support or stand behind? To me it looks like someone else is getting the revenue on behalf of wikipedia. If that is the case, it is a nasty exploitation.
So good that I installed it twice!
Works perfectly. I had to disable ad-blocker, which I will only do for wikipedia. They should feel special.
