I run the free version and do not delete the Ceph repos (especially since I'm using Ceph amongst my storage options):

    if [ -e /etc/apt/sources.list.d/ceph.list ]; then rm -rf /etc/apt/sources.list.d/ceph.list; fi;

At the very least run a sed command to just comment out any/all lines in the files instead of nuking them.

Or change the file extension to anything else than .list

I don't know why you got downvoted, because you are right. There is no problem with keeping the Ceph repos, and you can use it with the community repos.
