100% a push shot (in the modern context) and yes, I agree it should be a foul - but I was reading in another thread whereby the ruling was something along the lines of, smooth through the ball, not two sounds etc then it doesn't matter in tournaments during this time (maybe remembering wrong, but it seemed like some conflict on this between west and east coast Americans?)
In my eyes, a push shot is unacceptable in all forms and contexts.
