I think he's just pointing out current problems, as he's done many times. He likes to give talks and publicity to his project, as its maintainer, and that includes this sort of "what's going on with the project" talks.

I don't think he's unhappy. Frankly I think he's doing the right thing, and I say that as the founder of a project where I didn't do that sort of thing, but now realize I should have. This is what gets you contributors/donations/publicity.
