Yeah, I'm just speculating on the reason it was removed from the store - But that's the more interesting question. Why was this particular extension removed?

There are loads of other Ad Blockers that do what this extension claims to do and they are all still available in the store - so all the conspiracy theories in this thread about google blocking it because it hurts their ad revenue seem bogus.

As I said, I've only seen extensions removed from the store that were doing something malicious - Something the person who installed the extension wouldn't reasonably expect it to be doing.
