Thanks for the link and the analysis. Though since I still use Wikipedia for science and math, I will simply write my donation off as a personal loss and self-reminder not to blindly trust guilt-inducing, beseeching banners without doing research.

I don't object to donating and have done so several times but the alarming tone of the recent ads made me donate much higher than my usual amount. Will skip donating for years now to balance the ledger in my mind.
