Except that article is mostly speculation...and Verizon does not have the resources to run that much data through their networks. Not only that, but Verizon isn't being that open, at least not for a while. So the entire thing is an academic debate right now.
Besides, if Verizon did try this, Sprint would just up it's WIMAX commitment, AT&T would start blanketting the country with 3G, and T-Mobile would...still sit there. ;-)
And Comcast, Time Warner, et al would probably fight tooth and nail on that one.
Not to mention, Verizon Wireless is NOT wholely owned by Verizon, but is partially owned by Vodafone. So unless Verizon wants to buy out Voda for full control and profits they are cutting themselves out of money if they push more people onto the cell network.
