Fully agree with you there - building cloud-only stuff has always seemed foolish to me. Even Azure Functions can be done as e.g. simple C# programs which would be trivial-ish to port ovee to VMs.

But my concern is for those that have built something as Azure/AWS only, who are now stuck with the bed they've made. Sure, there are lessons to be learned here, but if the volume of these is too high, then there will be pushback on any meaningful change since it will be too expensive
