I won't belabor the point about kids/teenagers bullying/shaming peers. That's been going on for centuries. But I would suggest not getting too excited about Apple supporting RCS. Their announcement says "we will be adding support for RCS Universal Profile, the standard as currently published by the GSM Association." That's not exactly what Google uses, though they like to let you think that. Likely will still have Blue and Green bubbles to differentiate the levels of capability in each standard, the most important of which is security. Standard RCS is little more secure than SMS, so there should still be a visual indication of what your chat is using.
