The fuck you mean? Docker is literally licensed under a permissive license. You don't need to pay anyone to use it, modify it, or distribute it commercially.
The Docker website is a literal psyop that conflates Docker (the engine) and "Docker Desktop," which is a Docker management program with a GUI. The one you need a license for is the latter. They are going out of their way to confuse people, but it only hurts their cause because people assume they have to pay to use Docker commercially.
You can install Docker on WSL and use it for free. You can find another GUI management program that's free (most of them are bad, abandonware, or freemium).

Podman has the same license as far as I know.
