People are always quick to parrot this old thing, but I think it's propaganda. Apple seeds will absolutely produce edible fruit. Most is fine for eating, and if it's too sour, it'll make fine sauce or cider. Crab apples are a different species from domesticated apples. The apples we eat come from Asia originally, where crab apples are worldwide. Different parents.

I live in an old farming community and there are hundreds of feral apples around here. I've tasted dozens of them and have yet to find one that was not edible or even delicious.

Modern apples (most fruit really) are selected for transport and keeping. Not flavour or edibility.
