Re: The real reason
To be honest I'm always surprised that Google haven't just banned ad blockers from their plugin store. Why would they make it so easy for their customers to bypass their main source of revenue?
Similarly, I'm surprised that they've never made it harder to block ads on Youtube, I'd have thought it would be easy to block the video from playing until an advert had been played (or at least sent to the customer), but instead adblockers just stop the ads, and the videos play as soon as you click.
I should probably shut up and stop giving them ideas.
