The fact how simple it is to re-implement a large part of Docker because all it fundamentally is a bit of glue code to the kernel is the biggest problem Docker-the-company faced and still faces.

Where Docker adds real value is not (just) Docker Hub but Docker for Windows and Mac. The integrations offer a vastly superior experience than messing around with VirtualBox and Vagrant by hand (been there, done that) to achieve running Docker on one's development machine.

Nah, they should have prioritized building some sort of PaaS solution like CloudRun, Render or Fly so they can sell that to enterprises for $$$. Instead they did half-baked docker swarm which never really worked reliably and then lost ground to k8s rapidly

That's what people usually say but they have tried to do just that a few years ago and it didn't really work. Docker inc has been doing great since they have shifted towards even more standardization in their container runtime, and focused on dev tooling. They became profitable when they focused on Docker desktop and docker hub instead of trying to build a clunky alternative to kubernetes or yet another cloud orchestration tool/platform.
