Originally I wasn't even concerned about an adblocker being built-in. I was just afraid that it will be used as an argument against more powerful extensions.

But you brought up another point: I think it is in the nature of an adblocker, that it MUST be "elitist" to be actually useful. If every browser does "adblocking" by default, the ads will just adapt. That will be as useless as the HTTP-Header "dont-track-me".

Good, let ads adapt. Then the adblockers adapt once more. And so on, and so forth. If ads were delivered by the same source/domain (ie. it wasn't outsoured to an ad network who also do profiling) people would have less issues with them.
