There are no good adblockers today. Most of current "adblockers" remove DIV element just because it has id="ad", without analyzing if there is any advertisement inside it. Simply stupid.

And since many "adblockers" are not open-source, you never know what it is doing. Software may perform censorship of the world wide web, depending on what investors tell the programmers to do.

Imagine the investor is Apple. They can make adblocker remove the the results containing "android" from your google search. I think such scenario is quite possible in the future, if users blindly trust "adblockers".
