The real question, I ask, is "Opt Out" truly opt out as the name suggests. Personally I dont think it is. I also believe our government has something to do with Phorm, it would make sense, especially with the illegal downloads etc.
Personally, if this is implemented, it will cripple VM as a business. People will leave in the flock fulls.

You can choose, I think its complete and utter rubbish. SOmething isnt right here and we should all stand up for it. Its about time, ths country stopped trying to control its people to the point where we hae no freedom, whats next, monitoring when you go to the loo?
