I've just listened to the GRC Security Now! podcast, what a solid and informed item stating that Phorm is by far the worst of all these advertising leeches, the transcript of the episode also contains some wonderful quotes that could be used in the fight against Phorm if the guys over at GRC would let us.
I'm looking forward to #151 when they're going into more detail on the issue.
Well worth a listen, or have a look at the transcript.
