In my experience as a parent with two high-school-age kids, this is mostly a media-created narrative fueled by Google PR.

I've witnessed their many text chains, all of which are standards-based (green bubble) because some participants are Android users. When I asked about it explicitly their response was "that's not a thing" (at least in SoCal).

Note that I'm speaking in generalities. I have no doubt there are individual elite cliques where the alpha children demand that members have certain types of phones, wear certain types of clothing, ride certain models of ebikes, etc.
