I’m gonna nitpick and point out that you’re referring to the results of only one of twelve studies included in the review you linked to. From the abstract of the review:

This review found little agreement regarding the relative effectiveness of electric air dryers. However, most studies suggest that paper towels can dry hands efficiently, remove bacteria effectively, and cause less contamination of the washroom environment. From a hygiene viewpoint, paper towels are superior to electric air dryers.
