Wow, sneaking Google Analytics into an extension like this? Some people really have no morals
As can be seen by any statistic - be it the download/rate/comment ratios on any of the mobile app stores, or the Chrome extension stores, the vast majority of users will stay silent. Wanting to know a tiny bit about them is understandable.
Probably the only reason I remember it is because it felt like such a peculiar justification.
The other extension got some pretty shady backers on HN in the past as well. [1] I think that this kind of extension just attracts drama more than others.
