I'd argue that Docker has done that in a LOT of ways. The huge draw to AWS, from what I recall with my own experiences, was that it was cheaper than on-prem VMware licenses and hardware. So instead of virtualizing on proprietary hypervisors, firms outsourced their various technical and legal responsibilities to AWS. Now that Docker is more mature, largely open source, way less resource intensive, and can run on almost any compute hardware made in the last 15 years (or longer), the cost/benefit analysis starts to favor moving off AWS.

Also AWS used to give out free credits like free candy. I bet most of this is vendor lock in and a lot of institutional brain drain.
