In my opinion, selling a PaaS was fundamentally the wrong call when they could have licensed an enterprise version of the engine and taken a commission on every server in existence. This is more a Microsoft or RHEL type business rather than a second rate Pivotal or OpenShift, which in themselves are being mullered by EKS/AKS in enterprise.
The whole pitch towards legacy apps was also short termist distraction when investment dollars are all going to cloud native solutions. Legacy apps are a big business case but getting companies to invest in their legacy estate is still a tough ask. This angle should have been secondary to competing where they are naturally strong.
