I hope somebody at Microsoft read this. It goes far beyond security vulnerabilities. The Teams Linux client is barely usable. Chromebooks don't even have a client.

Could Microsoft expose an API and allow third party clients to be developed?

You'd think, but alas, no.

At least with the old Lync/Skype clients, you could flip them into UI-suppression mode and drive them with COM, to replace their UI with a custom application, if you wanted to make that investment.

Potentially you could cobble together enough Graph API calls to make a lackluster restricted-feature client, but it would be a mess.
