Level the playing field
If you do not allow them to take away the content, then MSO's have no reason to negotiate in good faith thus the content owners are hurt.
If you allow them to take away the content, then the MSO's are hurt because the subscribers are hurt and, as has been demonstrated time and time again, they will go else where.
Really the only thing the can do with this is fine both sides an equal amount per day while also not allowing the content from being blocked in any form. This will cause them both to want to resolve the issue ASAP as their bottom lines are affected and it wont be because one of them is getting hurt more than the other.
