I wonder if European Commission would be interested in adding this to their investigation, couple of hundred million dollars should be enough penalty for violating users privacy.
I certainly hope the penalty for illegally wiretapping hundreds of millions of people is more than $1 per head. I value the privacy of my conversations (and life) way more than that.
Besides, if I opt-in to this service, why should everyone who ever walks into my home or office be presumed to have made the same choice? What if I am a doctor or lawyer who is not legally allowed to make that choice?
