@mjg59 yeah not inherently, just most often in practice. its more of a tendency.
one of my bigger obsessions with free software is looking at ways that freedom can be effectively diminished without being explicitly violated.
note i prefer openbsd to gnu/linux because i think it does more to protect freedom 3, but i love any work done to remove non-free stuff from it too. if the goal is perfection there will be detours and setbacks, while the fsf paints things into corners.
