Which UX problem do you think it fixed? If I had to rate by the ability to successfully start a call and not have technical issues interrupt it, I'd rank Zoom, Teams, Slack, and Google Meet roughly equivalent — the quality isn't as good or robust as Facetime but that's also not designed for meetings or cross-platform.
I'd accept Google self-selecting out of the market with their incoherent messaging strategy but that has nothing do with UX other than not needing to tell people to uninstall the old apps and install the current one.
