Why did Pink criticize Macklemore's pro-Palestine performances?

Pink said her objection wasn't to Macklemore expressing pro-Palestine views themselves, but to something specific about how he performed them, and she has framed her criticism as standing up for her own people as a Jewish woman. She made these points in a lengthy statement expanding on her earlier call for him to be dropped from Ed Sheeran's tour, while also describing the backlash she's faced as harsher than expected [1]. The stories don't go further into the precise details of what in his performances she found objectionable.
