Where is this place that has 3 fiber ISP choices? It is hard enough to find residences with 1 choice of fiber ISP. I have yet to see a single residential location in the US that has more than one option for a fiber ISP.
Having any ISP competition at all is relatively new for the Seattle metro. It was essentially only Comcast for a decade. Now we have Centurylink in large parts of the city. I don’t think Google Fiber is widely available here.
Centurylink rates for 940/940 Mbps in Seattle are $65/mo, which isn’t as nice as $50, but not bad. Comcast charged like $80/mo (coax) for ~200/20 as recently as 2017.
