What is the appeal of getting them to cut costs down to nothing? It seems weird to me that people resent a budget of $70 million/year for the most useful website in existence. What would you rather the money be spent on?
On the other hand, if I choose to donate money to Wikmedia, 80% of it goes to other places, like their "content" sites, which consists of this bunch of mediocrity:
Wiktionary, Wikibooks, Wikiquote, Wikivoyage, Wikisource, Wikimedia Commons, Wikispecies, Wikinews, Wikiversity, and Wikidata.
I don't give a shit about any of these projects, the only one I really don't want to go away is Wikipedia, and the rest could die and I wouldn't even blink, except as those projects also support Wikipedia. Increase Wikipedia's expenses if you must! Double it! Triple it! Just don't pretend that the foundation is struggling to support the thing that most people donating actually care about.
