Agree. The author here probably just looked at a list, did no research and formed her own (uninformed) opinion.

Keep in mind that as FredandMarty commented, these are market-based salaries and that the candidate has the upper hand. With all the scrutiny that university presidents have been under the past decade (just look at UBC) not many want to dive into that work as those who have the skills and expertise can find quieter work elsewhere and for similar pay.
