First up, I actually agree that the specific fund donation here is highly sketchy, especially the way it bypassed the usual processes and in particular the conflict of interest involved with the counsel hopping jobs between the WMF and the recipient. So I'm not even going to try to justify it.

However, the WMF also does have a history of concrete actions to improve access to Wikipedia: it funds chapters around the world, seeds obscure language versions that would otherwise not be sustainable, and does stuff like sponsoring flights for students and Wikimedians living in poor countries to various Wiki conferences. I'm totally on board with this and I think it's a fine use of a reasonable portion of the Foundations' money, as long as it doesn't imperil the main mission, which it clearly doesn't.
