You take the term "lock-in" far too seriously.

Yes, one can migrate their entire CI/CD ecosystem, countless IAM policies across multiple AWS accounts in an organization, their lambdas, databases and S3 buckets over to Azure given enough time and money.

The thing is that most everything in the cloud is billed on subscription, and many core components of networked services need not be (except support). Open file server, self-hosted IAM and standards-based execution stacks. Don't like hosting your nginx on Vendor-A? Move it to Vendor-B.

Yes, the tradeoffs are costs. No, vendor "lock-in" is not the only component one should measure when deciding an architecture. Yes, "lock-in" can occur with on-prem software, and hardware, as well.

Yes, it's real and worthy of concern when a vendor knows they can squeeze you because you have no other choice and the level of effort to migrate is too high.
