Have you validated that this is true? I just pulled the extension to look at the source (it's not minified). It does have google analytics on it, but that is noted by the author in the extension.

All of the blocking logic is done client side, with a single web request that I could find (not posting any data).

What I mean is that you run code on your machine from a guy you know nothing about. It has full control and you have no idea what it does.

The average user does not know how to study the code before installing it.

Heck, I don't know it. How do you do it?
