The program in question is under a free software license that respects users'
freedom and community: https://www.gnu.org/philosophy/free-sw.html
But it does not work without another program (or, more probably, a library)
under a proprietary software license that does not respect users' freedom and
community.
As a consequence there actually actually is no way to use the free software
program in complete freedom. For instance, in the late 90s, KDE could not be
used in complete freedom: although it was free software, it depended on Qt,
which was, at that time, proprietary.
