No, but I'm also being generous in my engineering estimates to put Google in the least-flattering light. And the ISP's started this fight by blackmailing Google--don't bring a knife to a gunfight springs to mind.

Google won't take too much of a loss, if any. Once a fiber network is in place, it's almost maintenance-free for several years. In addition, Google built all their hardware from scratch to minimize cost.

Finally, you may find that Google Fiber turns the network over to the locality for anything too unprofitable. That's a win-win--the locality runs the network (and gains the profit of cable TV, etc.) and Google breaks the monopoly of the last mile.
