> I already spent 5 minutes explaining my wife how it's neither Hangouts nor Meet, even if it uses the same Google login.
Why would she care? It's a separate app. Just fire it up and start a videocall with someone. With Duo I can call friends on Apple devices, and the quality of the call is excellent. I use it to call my mom (in another city) any time I want to talk to her. She's a technophobe, but even she can answer the call and start chatting with me.
You case seem to be straightforward because your mom only uses one service. It’s a mess that you need to care about when you use four or five calling services.
There’s frustration on a lot of aspects, one of them for instance being that both Hangouts and Meets are integrated to Google Calendar, so if you use both a private and corporate gmail, you’ll get a link to one or the other depending on your meetings. Sometimes from the same calendar screen. Some people won’t care, but there’s enough cases where it will be a PITA to remember which one you’re using or will be using, just to get back to the right window for instance.
But really the main frustration is you can’t give someone a Duo address. Or a Google Meet address. You have to give them your email, and then negociate what service they can/are comfortable using. And ghey have to remember what was negociated.
At some point clear marketing becomes a user facing feature.
