People refer to it as VSCode, but do people really use VSCode or VSCodium? I personally use VSCodium. I think that is the most de-telemetry'd version of it, I think?

Not sure if VSCodium and others can use all the extensions, especially Microsoft ones like Copilot. I remember setting up something like that once and had to do a lot of fiddling to be able to use all the extensions I wanted. Gave up on it at some point.

As for people in general, safe bet in almost any topic is that most people won’t care. :) So yes most people use VSCode.
