Group MMS is terrible (group chats in general) and you can't really expect a group of people to all download and install a new app because one person has it. In all likelihood, you will simply be excluded or if it's important, you will be forced to use something like facebook messenger, google hangouts, instagram, etc which is worse than SMS.
To now argue that nothing can or should supplant it is just Applecronyism.
