It is an App Store monopoly problem. Take Google Android as a counterpart.
Android Open Source Project = VS Code (MIT codebase(
Android at Samsung and dozens other = VS Code with Microsoft EULA
Enforced Play Store in vendor phones = VS Code Extension Market Place (not accessible to any other competition)
Google offering dominant services = Microsoft Language Packages (both proprietary => user lock in)
Google abusing it (eg by marketing, subscriptions, ...) = Microsoft abusing it
So what is explained in that article is how you run a monopoly on an open source project. Julia and the DevDiv is doing that. That is understandable (she has to make money to get her bonus) but not good for the rest of us.
