Am not familiar with Rancher Desktop, but briefly looking at their website it has a Docker CLI dependency which surely would land it in the Docker licensing controversy space, no ?
Docker CLI and Docker engine are open source :) Docker Desktop for Windows/Mac are not. So as long as the dependency is on the open source components, AFAIK they'd be fine.
