Exactly my thought Tropical Island. When you consider that a lot of web users can't even see the difference between ads and content it's unlikely many would start to use apps to control scripts and display.
And even someone capable of doing so would not necessarily do it if he/she is searching for something. Not ALL ads are crap and useless and a web savvy user will know that.
