So.. let's say I host my source code with MS (GitHub), I develop using their web ide (visual studio code space) and then I deploy to their cloud (azure). Give it a decade and you'll have Microsoft specific developers and organizations who are locked in beyond rescue. It's always a fragmentation vs defragmentation battle.
Don’t need to give it a decade, you can find plenty now, or two decades ago. It’s not like Microsoft is a new entrant to the IDE market with VSCode or GiHub Codespaces (hint: the VS part of VSCode).
