So what? What does it change in practice? What's stopping anyone from creating their open source alternative if it bothers them? Now let's say they "extinguish" their extension ecosystem. Then they die and everyone switches to VSCodium and open-vsx for extensions. Again, what's the problem? I honestly think they're in a position where not only the EEE is not their strategy anymore, but also it's not even doable with the state of VSCode. Now, what exactly are your arguments?
