I find this incredibly hard to believe. And just because the Apple marketing department believes something is true, doesn't make it so.

Maybe I run in a weird crowd, but I've never met anyone who cares whether "text messages" are delivered over SMS or iMessage. In general most messaging I do happens over Signal, WhatsApp, Discord, or (in a few unfortunate cases) Instagram messenger.
