Here is the uncomfortable truth about adblocking, yes there will always be a small subset of people who do it but as you put more hurdles in front of people less and less people will do it, this June my ad rates are at least 10% higher than they normally would be and this is with a Linux audience. Google's goal isn't to stop adblocking it's to convince you that adblocking is too much of a challenge to be worth it so that you stop using it willingly, in other words, boil the frog.
