They weren’t forced to BY Sky…they were forced to because of a lack of funds, partially because they have to pay Sky to get their content shown.
Then why didn’t you say that in your opening post? It’s unclear, so you can see how I might have misunderstood it.
OK so if 75000 people sign the petition what will happen?
The petition will go to the government. Although I doubt it will do much, because if you read it, it’s very aggressive. It accuses Murdoch of extorting the BBC with the help of “cronies in government” (which suggests they are on his payroll, making it a conflict of interests and opening up the door to accusations of corruption). For one, that’s not a particularly diplomatic way of putting it, kind of biting the hand that feeds you. And secondly, if there are Murdochites in the government who wants this scheme to continue, then they’ll find a way to shut the petition down.
