When they can all share the same Electron implementation instead of individual copies it reduces memory quite a bit. I'm not trying to defend Electron way of development but I can see why they pushed WebView2.

By reusing the system webview? It's what web frameworks should've done.

What an insane take. Also, the parent comment is incorrect, because the WebView2 memory is clearly attributed for both Teams and new Outlook in Task Manager.

When has Microsoft not been dishonest and misleading? Being dishonest and misleading has been Microsoft's entire game plan since all the way back into the Bill Gates era.
