Well, shit. Google Fiber has been the least-bad residential ISP I've dealt with. They put the fear of Competition in all the other ISPs in town, giving us an immediate free speed boost years before Google Fiber actually made it to our neighborhood. But more than most Google projects, it's always been clear that they could at any time get bored with it and give up.
It sounds like Google Fiber’s underlying mission was successful: to improve the quality of Internet experience nationwide. They didn’t even have to undertake the difficulty and expense of an actual buildout in most cases!
