This is not going to get rid of peer pressure. That existed long before kids had phones and it will continue to be a problem with this.

Parents should be there to teach rather than just restrict. Kids will need to learn how to recognize and deal with peer pressure at some point.

Also Apple definitely benefits from peer pressure generally. Their devices are seen as status symbols, the dreaded green bubbles, maybe more. I wouldn't expect them to do anything to actually improve things in this area.
