If the solution is to force everyone to do everything the same way... that's a political solution, not technical. That solution could just as easily have been everyone is forced to do everything the same way on their local machine. Maybe its more politically expedient to move everyone to a completely different cloud stack than to fix/standardize the local one.

I'd expect internal support to be highly dependent on how terrible the alternative is. Beyond personal preferences, I'm really apprehensive about coupling all dev work to a single remote cloud provider. What happens if you lose internet access or when they inevitably go offline? In the case of the later, literally all work stops.
