I completely disagree that he went "full-blown" maxi in the article. He said himself that he is trying to be tech agnostic and not even try to decide which risks consumers should make, but rather ensure that securities laws are followed so that investors are protected.
Did he teach a class at MIT about bitcoin? Yes? Did he admit he's not a maxi in that class? Yes.
He even says that he doesn't think micro-payments will radically change things.
I do think he will come around, though...
