Do you really think SLY has the money and the manpower to take every end user to court and also they would have to prove the end user was actually watching their broadcast. Even if they could they would be tied up with courts dealing with cases for the next 30 years.
They can only realistically go for the supplier unless somebody is stupid enough to give SLY information about their supplier they would deserve to be prosecuted.
What about all the users that do not live in the UK, how could they prosecute them?
No users are not going to be prosecuted just suppliers
