The character assassination of the outgoing librarian (which is the bulk of this article) is pretty tasteless. The substance of the criticism is (a) the WaPo doesn't think that a fundraising programme he ran wasn as successful as it might have been (but still raised millions), compared to nothing, based entirely on a listing of scary-sounding expense reports, which includes, shockingly, Acela tickets, (b) he wasn't great on tech, which is a legitimate criticism, but hardly unique among senior government figures born in 1929, and (c) unnamed employee sources, and a single named 10-years retired employee, were happy he's retiring.

Wikipedia doesn't usually mince words around this, and in the five months since his retirement, nobody has thought to add a "Criticism" section.
