Docker CLI is free for commercial use, it's only docker desktop you have to pay for

I know, but companies legal or IT department make it easier, no docker of any kind being installed from https://www.docker.com.

Microsoft also is finally adding their own docker cli (wslc), due to having had enough pressure that many companies don't want to instal third party tools for Linux/Windows containers, even if API is compatible with docker daemon.

Apple is doing a similar approach on top of their virtualisation framework.
