Just took a quick look at BTN highlights. The live shot was the sideline camera and it didn't look too bad at all. The replay was baseline camera and you can see the shooter's hand go sideways from contact.
Doesn't matter what the shooter's hand does, the defender is entitled to his space, straight up. If Haarms went straight up with hands straight up, its not a foul. I have had to explain this to far too many people when reffing games.
