> That would mean using two different messaging apps, an annoyance that most people won't want to deal with... FWIW, most "normal" people I know (as in, not technologists who carry complex opinions about chat protocols and applications in general) seem to just use a ton of messaging apps to communicate with random people for various purposes? They do have a friction with respect to installing one they don't have yet, as it involves work that maybe they can avoid, but everyone seems to have and use and communicate using Facebook, Snapchat, SMS, and at least one account (if not multiple) on each of Instagram and TikTok. (Additionally, people I know who have international contacts -- whether due to being "professionals" or by way of family -- generally have WhatsApp.) It really is only a few techies I know (honestly, including me at times, though for what I think/hope are slightly different reasons: my issues often come down to how critical it is that I can have long-term log retention in useful searchable mechanisms... a big reason I refuse to use Signal as it doesn't even support backup correctly on iOS) who seem to get sad about using multiple apps (which should make sense, as if you know even only two people who are super picky then they probably just fail to communicate with each other at all because they end up in disjoint cliques: your "neighborhood"--which needs to include all your contacts, really, and so quickly knots together with "the world"--isn't going to settle on a single chat app... "normal people" find that level of "sorry: I only use X" stubborn and a-pragmatic ;P).
