That article is pretty unfair. The Wikimedia Foundation has started a lot of other projects since 2005, several of which are very useful and contribute to their general mission to bring knowledge to everyone. Wikibooks, Wikidata, and Wiktionary spring to mind, among others. They've also become the point of reference for almost everything for the entire internet-connected population, which legitimately requires more PR people, more lawyers, and much higher administrative costs, just to maintain their original level of quality in the face of adversarial governments, megacorporations, and every troll with a keyboard. The relative lack of scandals, disasters, and press attacks in the current climate is borderline miraculous.
Compare Wikimedia to, say, Mozilla. Another high-tech open-access-focused non-profit (sort of), and with 5x higher revenues ($500 million!). They've also spent most of it on new projects and skyrocketing administrative overhead. Yet their PR is much worse, they suffer falling market share, and nobody uses most of their side projects. Wikimedia is still efficient and effective given the arenas it competes in.
