Here are some more details on our blog: http://purplebox.ghostery.com/?p=1016023438
As far as the use of data, some of the products Evidon is now making are so new that the GhostRank information panel has not needed an update. We'll be modifying the wording to be clearer, but just to make sure, we never collect or use PII info, just the trackers information to use in products such as this: http://www.evidon.com/trackermap
In any case, here is a good post we've just put up on our blog that answers these concerns: http://purplebox.ghostery.com/?p=1016023438
Hardly anything Ghostery does. The rules are defined by Google and the wording is unfortunate but largely correct: any extension that needs access to tabs, content scripts, and requests/responses will get the same message. So, basically, any extensions for content blocking will ask for these including Adblock/ABP+, Script no, whatever.
