Wow thats bad, on just so many levels. Why is a publicly funded service selling tracking data, let alone one that handles, as it's primary function, confidential and privileged information about your medical history?

The author is right, heads should roll for this.

I'm not sure they sell it. If I'm reading their dialogue correctly, they appear to just give it away which is either a lie or even more worrying.

Agreed, this is wrong. Confidentiality when it comes to health matters needs to apply on the web, too. There's far too much scope for information gained using marketing tools on NHS websites for abuse.
