Cool example of the Magnus Effect

I'm curious why so many cfi's focus on Bernoulli when in reality the circulation pattern set up by the Magnus effect is the phenomena responsible for the differntial velocity above and below the wing, and therefore the pressure. It accelerates air above the top, and actually slows the air below. Of course the shape of the airfoil plays a big role , but it's circulation (Magnus) that leads to upwash, downwash and wingtip vortices.
Bernoulli I think describes why there is suction, not why the velocity is higher.
