The problem that I have with the way Apple does this has nothing whatsoever to do with me. It's their device, it is not possible for me to care any less about it.
No, the problem I have is that it becomes a severe bullying / exclusion tactic among kids. Now, kids will always find something to bully other kids about, but this one seems to hurt a lot because of the source of the ire and the inability to do anything about it (short of purchasing an Apple device).
My eldest was excluded from group chats with friends because they "ruined" the quality of pictures and videos by being in the group chat. These are friends mind you, not the sort of bullies the rest of us might've had. It's devastating to kids when their friends exclude them like this. What do you do? You can't complain about the technology not mattering, you can't reason with it, you can't say: "it gets better".
Kids these days have a very different relationship to technology. That relationship can seem weird or "wrong" to folks who remember a time before these ubiquitous devices. Crap patterns like this creating artificial walled gardens are not "novel" or "creative" ways to increase sales.
