All channels connected with Showtime (I'm sure someone here can help with what they are) can be boycotted and it will effect the ratings of the main company.Showtime doesn't care squat about ratings, only subscriptions. Showtime would gladly take the money whether anyone watched or not.
What is needed here is a storm of subscriber cancellation threats. I can't help.
I'm cancelling our Showtime subscription tomorrow; nothing worth watching on it anyway.........
