I agree that a flat wing will produce lift at a positive AOA even without an
airfoil shape - it just won't be as efficient as it would otherwise be if it
were shaped like an airfoil, and talk about pitch divergent...

Non-flat airfoil shapes help to increase the range of usable AOAs and reduce
drag, but a positive AOA is still required to generate lift.

Oh yeah, the article also pretty much discounts Bernoulli as having anything
to do with why a wing produces lift.

It is a common misconception.
