My biggest gripe with the Wikimedia Foundation is their clear biases in regards to what articles are allowed to cite. They'll allow citations from the conservative Heritage Foundation in an article describing a CIA massacre in South America. However, they won't allow citations from The Grayzone media because they claim that everything the Grayzone writes is fake news.
I would rather give my money to The Grayzone than to the Wikimedia foundation. And frankly, regardless of what your political predilictions are, giving money to independent journalists will always be better for society than giving money to the Wikimedia foundation.
