Poked a couple of journos and stories changed to reflect not VMO2 acquisition.
Yes, good point, of course Nexfibre would acquire the contracts that CityFibre had signed. Not a bad place to be having VMO2, Vodafone and TalkTalk on your fibre network.
Room for another insurgent altnet but perhaps that's all it'll be: Openreach, Liberty Global, and A N Other depending where you are in the country. Hyperoptic should be consumed in the not too distant, G.Network may be distressed soon, leaving Netomnia largest network other than the big two.
