Re: @msknight ... Thanks...
They probably already have offered such a service in preparation for it, so they can seem like good guys to consumers ("hey we're blocking the BAD ads but we know you want to see ads about things you are interested in!") while using it as leverage to make advertisers pay them premium rates for ads that Chrome won't block.
Of course we won't hear about this for a few years, because it will be protected by major NDAs in their contracts because the whole thing falls apart once people know the truth.
