The Wikipedia has been a focus for infiltration by cranks with axes to grind, socialist orators, pseudoscientific panic-mongers, prohibitionists, looters, thieves and wannabee dictators. Donate money if you must, but please donate to a worthy cause. The Wikipedia is NOT that worthy cause.
I personally consider the Libertarian Party a worthy cause. For similar reasons I have thought of giving to the NRA, LEAP (policemen against Prohibition), Naral (pro-choice) and other causes to which I am sympathetic. But I conclude that none of them can possibly succeed if LP.org fails. I do on occasion turn a tiny contribution over to Project Gutenberg the way I’d pay library dues, but this has a lot to do with a linguist’s profession and need for research material.
Resumo: não dê dinheiro para a Wikipédia. Foram infiltrados por hostes contrárias à liberdade humana e à honestidade (que chegam a ser a mesma coisa).
