AdBlock filters and censors content. Personally, that's why I don't use it. I don't want to see a censored internet, I want to see it as it was intended to be seen. If that means I get pissed with a website doing intrusive advertising and never go back there, then that's a good thing, as it's good feedback for that website. There is more than enough choice on the internet which means I will go to websites that play nice.
Adblock usage has been around 1% for the last few years, so I don't see any sign it'll increase.
