Wasn't Foucault a professor? He just, essentially, refuted himself (because he's part of that teaching system, which appears to disseminate knowledge, and is really about maintaining a certain social class in power).
You pass over the word "simply" there: Foucault doesn't mean that universities do not disseminate knowledge, but that they do not _only_ disseminate knowledge, they also maintain a certain class system. I don't think he would exempt himself from that, but poststructuralism is not usually interested in the actions of individuals as much as the way societies are structured (such as, for example, having universities which are organized in certain ways).
Right, but that still leaves Foucault as part of that system. It's a biased system, not to be taken at face value or as objectively committed to truth as it appears or claims to be. But that applies to Foucault and his thought and teaching as much as it does to the rest of what the universities teach.
This is not profound. Human activity is imperfect. That's the case whether the human in question is a famous tenured professor or a hermit on a mountaintop. Perhaps politicians ought to pretend infallibility, but serious thinkers shouldn't. It's possible that we must consider many ideas that aren't true in any objective sense, in order to get closer to the the truth ourselves.
