Ariana Grande is a gifted Soprano with a god given vocal range, however, I think using that as a reason to have a problem with her is rather odd. If anything, she doesn't abuse her voice. I actually remember her having an interview saying she doesn't sing Whistle Notes (anything at or above Eb6) live because she doesn't have the proper technique yet to hit them. Also she can easily sing F5's all day ("Every DAAAAAAYY!" in Break Free). Also she hits G#5/Ab5 in Problem (and realize that i've GOT) in an amazing belt. I mean if my comfortable range was in that area, I would sing like that all the time. Every singer shows off and I bet you, if you had a voice like hers, you would definitely show off. You can't knock a singer down for singing in their comfortable range. Yes she needs to learn how to use her voice to hit the whistle notes, but I bet you she knows what she's doing with her voice. I rarely hear her strain, I would go as far to say she uses her Mix to hit her high notes. She knows what she is doing. I'm an Ariana Stan, yes, but there are plenty of other artists that do show off. (Jessie J, Mariah Carey, Beyonce, Christina Aguilera (the queen of showing off)).
