Yes, but both would save on Docker licenses and it isn't as if anyone would pay for Docker tooling on Linux anyway.

So how does Docker capitalise on this new tool?

They keep trying to stay relevant in a world where containers have become commodity.

Sandboxes are free, distributed outside of Docker Desktop, no license fee required - money is made on enterprise governance and cloud offerings.

You can call containers a commodity, or an industry standard? Feels like that is more an emotional argument than anything else.

You actually do not need any licence (though a docker account is needed) to use docker sandboxes with the CLI. It's at least what the linked page says (ans my own experience ;)
