You sure your bill goes beyond specifying that you are paying the
extra cost for Showtime and actually specifies what shows you will get
on Showtime? Yeah, didn't think so.
Only the dead don't have to concern themselves with change. You paid
Comcast for Showtime access. They gave you access. Comcast doesn't
own Showtime. Drop Showtime and send Showtime a message if you don't
like what Showtime did with their programming.
