I'm trying to empathize with the devs and publishers and thinking from the business side of things I can understand why they push for the constant-online DRM schemes; I have to point out that the business mind is not always the reasonable mind.
The publishers' logic suggests that all logged players are legitimate customers, therefore all software with online-only DRM will only be purchased legitimately. In a perfect world where internet is free, global, and unrestricted, perhaps (they're also not accounting for good old-fashioned physical theft). In the mean time, it doesn't make much sense because it restricts the customers and, from a business sense, it limits the sales projection. The potential (and likely) outcome is for publishers to consider bigger budget games, in the hopes of raising the sales projections, which will result in a higher price point for the product. We all saw this happen when the price point of new PC games went from $49.99 to $59.99. This would also point out how neglectful the marketeers are of their primary demographic: the average PC gamer.
The current cost of new PC games is being criticized but how much the scrutiny will sway the publishers will only be told in time. I just hope that
