Cable cards have a debug interface to allow the user to query the state of the cable card. Accessing that interface doesn't allow you to change the encryption methods on the cablecard. ISP gear has often been terrible, notably in situations of bufferbloat. If you don't want to fix your crappy gear, at least give the users an interface to diagnose the problem and possibly fix it on their end. And yes, certain things like bufferbloat can be fixed at the user's end.
