IBM Cloud Foundry (formerly Bluemix) isn't quite deprecated but the container manager inside CF was stuck on the deprecated DEAs rather than Diego long after Pivotal and others moved on. They moved to Diego last year I think but very slowly.

And then they rebranded IBM Spectrum Conductor for Containers (look it up!), a Kubernetes snowflake they came up with, into IBM Cloud Private, because Kubernetes will solve all problems, the issues MUST have been leading with a PaaS and not a CaaS, right?

Other observations are spot on

Disclaimer, I compete with IBM and have to deal with their account team shenanigans, though parts of IBM are better than others and even can be good partners.
