Re: @ "Your data probably isn't that interesting or important."
"Important data" being collected is clearly those UK users who havent paid for TV license, the premise being that no one would ever really opt out of the BBC service.
It's pretty much the exact opposite. By moving all the radio stuff from iPlayer to Sounds, it means anyone can access the radio stuff without having to register with iPlayer and "agree" that they have a license. The license fee may well fund BBC Radio but you don't need a licence to use a radio,
