Baloney. All the major clouds offer managed k8s. And using k8s in no way precludes you from integrating with services that are not on k8s (of course though, k8s can run anything you can containerize). So AWS has vastly more "lock-in" debt than k8s.

To replace an AWS service, you just plug in a different service integration, or use a literal API complete clone. To replace the use of any part of K8s with something non-K8s, you basically have to replace all your use of anything in K8s. So the debt is much higher with k8s because it takes much more engineering work to get off it and it's not compatible with anything but itself.

Furthermore, just because someone has a managed k8s doesn't make it less lock-in or less work. With AWS you don't need to use a cluster of anything. With k8s you are signing yourself up to tons of complex services and specific design and operation paradigms. With AWS you have no such inherent restrictions.

K8s is inherently more complex and difficult to use than AWS services, which aren't even a good comparison because they are so simple by comparison.
