The difference is that Canonical forces the contributions ownership to be handed over, while RedHat plays by accepted opensource practices. So while Canonical might have good initial ideas, the way they manage projects really kills them, e.g. snaps properly opensources might have been successful, instead they enforces the use of their proprietary server and ignore community requests (like moving /snap to /var/snap or making it configurable or allowing different servers/sources for snaps, while you can relatively easily make your own flatpak server and have users add the repo to their systems).
