Contador probably is a little pissed, though i imagine he's much happier now in paris than he was earlier in the tour.
I don't know whether Contador realized it or not (or cares) but Armstrong being in the Tour and being on Astana and being 3rd on the podium means that a heck of a lot of people know the name of Alberto Contador and his 4 victories who otherwise would have no idea and paid little attention. Regardless of what sort of media spin is put on which rider, anywhere there was Armstrong, there was Contador. "There's no such thing as bad publicity."
