Nobody is paying for BBC Worldwide (at least to view this article, apart from advertisement). So why not show it to UK citizens? It wouldn't take anything away from BBC or BBC Worldwide. Maybe some more clicks on advertisements from people in the UK, so more revenue. Also if BBC Worldwide is showing content to everybody but UK citizens to subsidize BBC to produce other content for UK citizens, why not show the BBC Worldwide content in the first place (if the goal is to have more content in the UK)?
