Docker Desktop is not open source, but the Docker container engine is. Also, runc, which is the actual container runtime, is not only open source, but was created by docker but is also what gets used by podman. podman is very nearly just a fork with the daemon and socket removed, which would not have been possible if docker hadn't been open source.
