I'm not sure who publishes this blog but it looks like to me like a marketing resource of one or several of the private sector Nextgen contractors. In fact it almost looks like the handywork of Robert Poole and the Reason Foundations - a private-sector "think tank" (and I'm using the work "think" very loosely), whose primary goal is to deregulate and contract out virtually all goverment services.
The article "Air traffic service provision – business logic in reverse?" is riddled with conjecture and spin. A more objective and accurate look at ATC financing can be found here
I'm not sure when people are going to realize that concepts employed in European ATC may not work in the US. The sheer volume of air traffic we have to contend with in this country makes many of these ATS and ATM concepts impossible to pull off. The US government needs to be very careful in the coming years or we will end up throwing billions of taxpayer dollars away on a pipe-dream - all because of a full-court marketing blitz which includes industry blogs like Roger-Wilco.
