Yeah, because he's 1. on their side, and 2. necessary to win the war. Not to mention 3. he didn't choose to become a Hollow, and being 1/2 Quincy (his mother was Echt) isn't as bad as you seem to think it is. He's a freaking Special War Power, in case you forgot. And as for what Ten said, it still holds true: Ichigo isn't a Hollow himself, while Grimmjow straight-up is.
