Given that there exist people that hold this opinion, their own view about using an ad blocker is not at all in the same context than in the prisoners dilemma.
Thus the dilemma is biased, to an extent directly proportional to the number of people holding this opinion.
If it is biased, the standard game theory analysis does not apply directly. i.e. the best move might not be to suffer ads for no long term gain.
More prosaically, I do not care in the slightest if people living in selling ads disappeared completely from internet. They are a cancer, ads are a cancer to the utopia that internet was for a short time.
We need come back to this state. We will, actually, by empowering users.
