2. Content publishers have to be able to make enough money so that they continue to find it economical to produce content.
"First click free" was the compromise solution for this. Google's incentives actually run both ways - if they couldn't use paywalls, most content sites would probably use AdSense or DoubleClick, both Google products. But it's unlikely that a site like The Economist or The New York Times could continue to produce quality articles off AdSense revenue alone.
