Okay, so you got a free ad plugin, and you’re insulted that the developer advertises on the config screens?
Either
a) ironically you’re also insulted when you see advertising on a website or
b) you’re looking to lower his average review rating.
I see much more advertising on Yoast, and Image Elevator (both great plugins) but if I’m too tight to pay a dev for their hard work, I’m not about to complain!
