Google Fiber's biggest hook has always been its $70 gigabit internet access, but there has usually been a far more frugal option: you could get free 5Mbps service if you were willing to pay a construction fee. However, that choice appears to be going away in at least one city. Google has quietly dropped that free tier in Kansas City, its first Fiber area, and has replaced it with a 100Mbps option that costs $50 per month. Anyone using the free tier has until May 19th to say they want to keep it. The company hasn't explained the move (we've asked Google for comment), but customers in Austin and Provo still have that choice; Atlanta never had it to start with. Also, this doesn't change Google's plan to offer free service in low-income areas.
