VSCode isn't a gift to developers. It's a marketing tool.

Why can't it be both? Microsoft has been doing great things recently, with VSCode, Typescript, C#. Of course maybe it's the first step of EEE. I'm personally worried about the VSCode/developing in containers that's closed source/Github/NPM acquisition, that sounds like they're preparing some kind of best of class developing experience (probably linked with Azure too) that will be proprieteray. But for now they remain well behaved, and everything until now is open source.
