My letter to the NHS Choices Team dated 2010-11-30
Hi Team NHS Choices,
So, I just thought I would let you know that, as per my blog post, the NHS Choices website is sharing information with Facebook on pages which DONT have the Facebook Like button, as pointed out by this person, as well as being on my blog post for the last few days:
Do have a look at the following page on your website, there is NO like button, and the same data exchange is STILL happening with Facebook.
The following screenshot illustrates this. People are free to replicate, all you need is Firefox and the Firebug plugin (both free and open source).
I also talked about how there is a German website which changed the manner in which it implemented the Like button functionality in a non-intrusive manner. That is, a manner which does NOT send any information to Facebook.com unless the user ACTIVELY CLICKS (i.e. OPT-IN) the Like button; quoting my blog post.
