The elephant in the room, of course, is that this is literally only a problem in the United States. Everywhere else in the world, folks are totally fine using messaging apps. WhatsApp is pretty popular worldwide, and there are regional favorites too. But, the point is, it’s only in the States that people seem to be against this idea. The answer for why is very much up for debate, but the conversation is, at this point, just getting exhausting.
Can confirm, as a Brit. We probably would have a sardonic explanation for why only people in the States are against using other messengers too...
I still really miss Google Hangouts. It was integrated with Gmail as a web interface. The web and mobile app synced perfectly. You could use SMS/MMS, or chat, seamlessly in the same interface. Contacts worked correctly. SMS and chat history saved to Gmail so all the text was searchable. It was AMAZING and Google killed it for no reason, only to later replace it with inferior options.
Edit: oh yeah, you could also make phone calls, or group voice and video calls using the same app/web interface.
