Isn't the Stockholm fiber company you mentioned an inherent monopoly, then? Assuming that they're the ISP as well? Or can independent ISPs run their service on the fiber owned by this company?
> Stokab was seen as a public infrastructure company by the City Council, much like a public organisation responsible for roads. As a consequence, Stokab was not allowed to sell active services, and was required to sell to any potential purchaser on a non-discriminatory basis
