Eh? They have created a loophole to get people to pay for BBC iPlayer access, they have not closed anything.
The loophole was to get BBC television without paying for it, by way of watching it after it was aired on live television.
That is the loophole that they have closed.
A loophole, from wikipedia;
A loophole is an ambiguity or inadequacy in a system, such as a law or security, which can be used to circumvent or otherwise avoid the intent, implied or explicitly stated, of the system.
