He didn't say he didn't want to hire former entrepreneurs - you are saying that. He said don't be misleading about your previous position. If you say you are a CEO of a company I expect at least > 1, otherwise are you a chief of yourself? It's incredibly misleading.
Also there's a huge difference between being a CEO of a one person company (don't have to deal with another human being) and a > 1 person team. As the team size increases, the title becomes increasingly more meaningful. You are free to draw the line wherever you want, but allowing it to rest on a 1 person team is pretty close to lying.
