TV service box

something I do not understand when you get TV service from Comcast the service box comes with a controller.  you have to pay extra each and every month for the controller.  $12/mo.   if you add additional TVs to the service each service box comes with a controller and you pay the $12/mo for it as well.  I really think Comcast could and should provide the first TV on their service with a controller as part of the initial connection.  

can I start TV service without the comcast service box?  and not pay the extra $12/mo.  it adds up over the contract time period and should just be included.
