>The revenue stream won't remain intact. This lowers the effectiveness of ads in the long run, reducing the price of ads and reducing the revenue for content producers. That would only be true if everybody hearing the ad responded to it. Obviously that doesn't happen, and there's an implicit assumption in advertising models that only some percentage of the listeners/viewers will respond to the ads. People blocking the ads are unlikely to respond anyway, so whether they block the ads or not doesn't make much difference in the long run.
