It’s not the majority of interactions but it was common enough in high school and college that it became a VERY decisive topic. It seemed the Apple users who didn’t bully anyone were unaware it was happening, and the android users, whether or not they were bullied, were always mad about the bullying, which, from the perspective of average iPhone users, made it feel like android users were constantly nagging them, which just widened the cultural gap between the two groups.
So if someone who had an iphone learned you used android, there’s an equal chance you’d get someone who was a bully for no reason or someone who assumed you were combative about it and either way looked down on you for it. It was an unfortunate situation.
