It doesn't have to be this way. Messaging isn't complicated. We solved this more than a decade ago. You have five incompatible messaging apps on your phone because greed drives companies to ignore compatibility and optimize for vendor lock-in. https://www.linuxjournal.com/content/lessons-vendor-lock-messaging
I miss Yahoo's IM as it was a good tool to use to start a live game with a friend... I used to play checkers with my daughter .... many years ago.
@kyle OK, for companies like FB and big G, but what's the explanation for Signal and Telegram not trying to make things compatible? I don't think they're making money out of their apps, are they? Or worse, for Signal not being able to send an encrypted SMS to SIlence?
