It doesn't control for men working longer hours, more overtime, riskier working conditions, outside vs inside work, career choices, fringe benefit choices, taking care of children and other family members, and a dozen or so other things that are deeply divided by gender.

Naturally if the article were framed by choice rather than something intended to mislead one into believing this is study on equal pay for equal work, the click bait value would be severely diminished.
