"must not": stance should be enforced, aka regulation. "manage their system in an anti-competitive way...": do something against the principles of net neutrality. It certainly sounds like support for net neutrality regulation, which has not been implemented outside of Title II rules. If the argument is that net neutrality should be enforced in a different way, there must be a different way. Currently there is not, so we must be talking about title II.
