i agree with you that CC-by-nc is a bad license for the default skin.
For example it's a reason to keep roundcube out of linux/bsd/...

i don't know whether relicensing the default skin is an option. if not,
then a new default skin with a more permissive, really free license
would be necessary.

FreeBSD, OpenBSD, NetBSD, Ubuntu, Debian and Fedora all have roundcube
available as package/port, and they would need to drop/substitude the
skin in order to update the package/port to latest version.

yes, version 3 of CC-by-sa would be good. even better would be a more
permissive license. for debians point of view (as an example) see
