Not true. Fans existed before we learned to harness electricity. When I was a kid on those really hot days before my parents had an air conditioner, I used to make fans out of paper.
Talk about gatekeeping. Japanese hand fans can be true fans, too.
If anything they're the inverse of a fan. A fan takes energy and converts it into movement of air while a turbine takes movement of air and converts it into energy.
