Hey - I'd love it if companies would do that too. But in the mean time... I'm not enough of an ass to throw away the solutions that work.
That said - Webex is not an electron app (Appears to be QT...). Teams is terrible by itself (no electron needed). Other apps do just fine... So I'm not sure what it is you think you're comparing.
Slack/Discord/Etcher are all electron, and frankly they work fine (etcher is even nice).
So between "You're on linux and we don't support that" vs "Here's a working app with company support (electron based)"... I know which I'd pick.
