If it had nothing to do with newton, then choppers would not have a problem with downwash. I find choppers particularly interesting elephant in the room, as they are nothing but planes with rotating wings. Yet, somehow, we accept chopper downwash as normal, and keep saying that downwash from non-rotating wings has nothing to do with lift. It just shows how dogmatic "science" is.
Personally, I think coanda effect and newton explain lift quite well, at least on the macro level.
PS: nasa has a list of incorrect theory of flight published for quite some time:
