This is a market exit, wherein Google is making Louisville Metro whole for damage done to our roads while rolling out a service to a tiny fraction of the metro only to give up and walk out.
Just got another one to add to the list.
"We would need to essentially rebuild our entire network in Louisville to provide the great service that Google Fiber is known for, and that's just not the right business decision for us."
That's exactly what the shareholders want to hear. Capitalism's myopic focus on "maximizing shareholder returns" will usually choose the cheaper option over doing the Right Thing.
If they manage to get an initial positive result and have some publicity, then the project is basically done. No one has interest in it anymore.
