Here in Switzerland the fiber is owned by the regional utility company (power company for example). I think by law they have to allow every ISP to use it.
Now everyone (or almost everyone) in Switzerland can have fiber internet with gbit up and down.
About 30% of households in Switzerland have access to fiber, versus 25% in the US. Switzerland doesn’t impose unbundling on fiber. The major fiber operator, Swisscom, owns its own lines.
85% of Americans can also get 100 Mbps. It sounds like you might be in some place like Zurich, where the local power company deployed fiber and allows ISP to provide services over it. That’s a good model, but it’s not legally required. For the most part, Swiss telecom regulation is very similar to that in the United States.
