Really? I’ve had employers pay for my Jetbrains subscription.
Zed's vision is that the editor is free and you're paying basically for Teams-lite.
If you're a big company, you're already using a service like Teams, Slack, Zoom, etc.
If you're a small company, then there's free alternatives like Discord.
And say you want to talk to someone other than a programmer, then you'd need something else anyway. Because a project manager wouldn't need an IDE installed.
I have never worked at a place that uses Jetbrains products which does not pay for their premium offering.
