It sort of becomes a people problem as people use messaging to communicate and organize events and exclude you because you'll break group chats.

Probably not a big issue if you already have a solid social circle of old tight friends who don't care about you breaking chats as they can also call you, but it can be huge issue when you move to a new city and trying to make new friend, as any extra friction you add to groups lessens your chances of being accepted and invited further.

Yeah, people can be quite lazy and petty even about such trivial things, when they don't know you and don't have any attachment to you yet, and you breaking group chats won't improve your first impressions and chances of being accepted. Hence the ever increasing loneliness crisis we're facing.

Thank fuck I live in Europe where nobody uses iMessage for group chats. Honestly fuck Apple for creating that unnecessary friction, it's not like they couldn't have accommodated blue bubbles to not break group chats but it's more profitable to emotionally extort people to buy your iJunk by making them feel outsiders.
