It's strange to me that Google would go out of its way to implement such a feature for the UK. Google does censor certain videos for specific countries' sensitivities, simply because by not doing so, youtube.com will be repeatedly shut down by the respective courts.

But why the UK? It seems that they've committed to the path of censoring the Internet like some authoritarian regime, but it makes me wonder what happened behind closed doors between the parliament and Google management that would lead this to happen.
