I'm not aware that Liberty have expressed a formal opinion on net neutrality or the various recent suggestions that Internet access should now be considered a fundamental human right, though if anyone has seen something relevant then I would be interested to read it.

I suspect Liberty are more concerned right now with the various mass Internet snooping provisions that seem to keep cropping up. Net neutrality seems a little on the commercial side and perhaps a little below the radar of an organisation that is campaigning against things on the level of torture, detention without trial, freedom to protest peacefully, etc.
