Comcast or any other provider is under no obligation to pay them any money for content which until a few days ago was free.
This is a part of a long line of dumb decisions by Universal Sports. First they would let you watch events for free on their website. Then they made it so you can pay per year or monthly and now you have to pay an exuberant amount or money for each event and no monthly or yearly options anymore.
I will miss watching alpine skiing, but I hope Universal Sports comes to their senses after their ratings drop so low that no one would want to advertise on them anymore.
