I'm not sure if I'm in two minds about it or not . There's a strong argument that the BBC wastes money (eyewatering salaries, etc) and this is merely a way of offsetting their profligacy, and many people who have to pay it don't use the "terrestrial" channels much these days anyway.
I think they might have been better handing the administration of it back to the Government and calling it a "Communications Tax" or somesuch. What do you think?
