Third one is probably extracted from the last two and colored by personal experience. I would tend to agree with the author though "appalling" is a little too strong. When I had a professor who was very obviously on the spectrum the class was often difficult due to either communication issues or assumptions about student skill level. It's not a universal truth, of course, but common enough in my Math and CS classes many of them were often frustrating to take. Stereotypes are often built in reality and while the author's language was strong I don't think the greater point they are making is necessarily wrong, nor unsupported by science as you seem to suggest.
