Well, most of their extensions to VSCode are proprietary. When their dominance in software development becomes irreversible, it's obvious that they will close things down and create new sources of income. The incentives are clear.
that's how effective eee is, you don't know (or likely care) where MS ripped all this code.
This is not an accident. It's the point.
If Microsoft want to develop some proprietary extensions for VSCode it’s fine, everyone has this right. It has nothing to do with EEE.
