Add this to the list of petty things GM has done over the decision to remove CarPlay from their vehicles. The OnStar Facebook page had an add up where they are promoting Apple Music in GM cars with an OnStar subscription. Well people were not happy that they had to subscribe to OnStar just to get Apple Music in their cars, so the comments were of course negative towards GM removing CarPlay just so they could charge users for more subscriptions. And guess what GM did after that? They shut down the comments on their post. Safe to say GM will continue to lose customers over this.
