I half agree with you. We just went through an ECS to EKS migration, and we're still incredibly dependent on AWS. The hard part isn't the container orchestration system or even containerizing your workload - it's all the other crap you need to develop and maintain around it. Your databases, networking stack, MQ brokers, secrets managers, and everything else are still stuck to whatever cloud provider you're using.

EKS really isn't much harder to build out than ECS - but it doesn't set you up to be much more cloud agnostic.
