Agreed. And you would think most paranoid HN types would too.

Maybe I'm foggy on the history. But isn't this like Fork #4 or #5 of some previous AdBlock extension?

Seems like the only business model for this type of extension is "selling out" for certain ads. And then the cycle repeats and forum posters tell you to install qBlock Omega or whatever. Maybe Mozilla doesn't want to get in the middle of this?
