In the second paragraph (though really, its just a statement...) on the preferences page -- no need to navigate to another page, and they tell it to you in plain english. Once again, you have to opt-in, so if you opt-in without knowing what it does it's your own fault and you're being a dumb user:

When you enable GhostRank, Ghostery collects anonymous data about the trackers you've encountered and the sites on which they were placed. This data is about tracking elements and the webpages on which they are found, not you or your browsing habits.

Online marketing companies need better visibility into real-world applications of their technologies and those owned by their competitors. GhostRank data is sold as reports to businesses to help them market to consumers more transparently, better manage their web properties, and comply with privacy standards.

Actually, I'd completely forgotten about GhostRank, the opt-in data collection service. The sneaky part I was referring to was just the default setting to add new trackers but not block them. I don't think any users have the expectation that updates will work that way.

I'd argue that Ghostery should come with a default configuration of ALL trackers and cookies blocked. I'd argue even more strenuously that after the user configures Ghostery manually to do so, ALL should continue to mean ALL even after updates. Ghostery currently has 700 3P cookies in their database, and almost 1700 trackers. There is no valid argument, imho, that a user who configures to block ALL really means "block ALL right now, but if you see any new ones, I would really like to try them out first!"

However, I mostly agree that Evidon has been up front and straightforward about what they do and how they do it. I want to like Ghostery. I do like Ghostery. This little bit of sneakiness though, honestly, taints the whole operation. You can call it an oversight, and I will agree that it can't possibly have much marginal value to Evidon...but it's somewhere between tone-deafness and carelessness, two qualities that call for heightened vigilance.

Your argument would be much better placed in our support forum. There, we do see much more opinions that are not the same, and the conclusions we draw are based on a bunch of inputs, but our support forum is probably the #1 place for issues we look at. Blocking pre-selections are currently slotted for mid-2014 because its actually a low priority item according to the votes we see.

If you feel strongly that your opinion is important and should be prioritized, please create relevant topic here: https://getsatisfaction.com/ghostery/ and gather support to change it so we address it quicker.

To be fair, if those recordings are time-stamped, it probably does leak information about user browsing habits.

Anonymizing data is hard.

Assuming they're adhering to privacy standards, the anonymization should be reported in aggregates and not like "{UUID} at {TIMESTAMP} reported {TRACKERS} at {URI}"
