Not just Kubernetes
Once you're committed to any cloud technology or provider it's remarkably difficult to extricate yourself. It's not just a matter of contractual tie-ins - it's about actually recovering your data and ensuring your processes continue to operate. Some time back I investigated two mainstream cloud based SaaS "office services" and found that their internal data formats were sufficiently different that you couldn't transfer files between them without utterly corrupting the presentation of documents.
