What the guy should do.. is to simply cancel the service.
Instead of going into a five hour back and forth discussion with them I would have put it in writing, highlighted the part of the contract that gave him that right..and sent it to them.
Following his long spiel, here's what the contract apparently says..
"In the event that HNS modifies this Agreement, the Service or related pricing or billing terms, you may immediately terminate your account and this Agreement. Subject to your payment of the termination charges herein described, you may also do so at any other time and for any reason on written notice to HNS."
They modified the agreement by now instituting new downloading requirements and so, according to those previously agreed on terms, he gets to cancel at no cost.
