Wikipedia is one of the highest-traffic Internet sites worldwide, and it's still being run on a comparatively shoestring budget. It's also an ongoing project, so the usual claim that technical hosting expenses are only a few percent of what's being spent on it overall is misguided. No one would care about hosting a dead encyclopedia

Keeping volunteers editors around is also a harder problem today than it was a decade ago or so, as purely passive consumption use of the Internet has exploded and overtaken the former model of a largely volunteer-run network. Wikipedia is just about managing it today with its current resources; if it had more, it could do better and launch a greater amount of technically compelling projects that would ultimately further its mission. (Already today, Wikidata, one of the more recently-created projects, is getting more edits over time than the largest Wikipedia and acting as a much-needed "hub" of the Semantic Web and Linked Data, which sees much use by the largest tech companies.)
