I don't think that alone is an issue. It could be seen as just commercializing the research he had done in the university setting. He would have to disclose this in publications (and perhaps he didn't). The university would have to approve (and take their cut). The issue is he seems to have fabricated results that prompted large companies to look for testing and certification and he was there with open arms (and pockets). If some other lab had come out and said "these products don't contain what they say they do" and the vitamin companies contracted his lab, then he wouldn't be in this situation.
