The Spotify privacy backlash: what is my personal data really worth? | Paul Mason

We are living in an era where big companies want to exploit the information we've given them for free. This powerful knowledge could be used for good - or to create entire business empires

"With your permission, we may collect information stored on your mobile device, such as contacts, photos, or media files ..." No, that wasn't GCHQ - it was the new terms of service imposed by Spotify, prompting user-outcry last week. Within 24 hours, the music-streaming service had to clarify that it will allow individual opt-outs. But, it was an example of the pressure tech firms are under to monopolise aggregated consumer data.

As well as my photos, contacts, audio and video, Spotify wants the right to collect data not just on my location "but the speed of your movements, such as whether you are running, walking, or in transit". It would see what I post and like on Facebook and it will store my credit card information, share it with payment processors and use all of this to fire adverts at me.
