Yeah, believe me, I'm not a fan of the misapplication and misunderstanding of much of this work. It's a bitter lesson in why making one's ideas clear in straightforward prose is so essential. I think Foucault at least, could be absolved from the notion that he intended any kind of said misapplication. Some other philosophers however, I think we're just straight up hacks that exploited the vogue of confusing language and weak metalingual philosophizing (Derrida, coughcough). If only we got students to read Wittgenstein first and save them from all the sophist language games.
