Hello fellow dinosaur! We've not yet gone extinct, despite what the hip kids say...
Yes, you can use video conferencing solutions for asynchronous one-to-one communications, much like you can use a clothes iron as a hammer, the sole interest is that those apps are terribly trendy in 2022, while email has long gone out of fashion. And you wouldn't want to be seen dead using such an uncool program, would you. You'd look terminally unstylish.
BTW, about being proprietary: They obviously are, because of lock-in: If you can't escape, you're easier monetizable. General, open standards prevent monetization.
