"Why do Australians insist on making proper home broadband a political issue?"
One party wants to throw the public an interim bone (FTTN, HFC) and then sell it all off, whereas the other wanted it to be FTTP and then sell it off. So I don't see the political difference.
I saw the PM saying recently "Optus could upgrade its HFC for a modest cost". Apart from the fact that NBN clearly deemed it too expensive to upgrade the Optus HFC, meaning that the PM lied, he also revealed his party's real intentions: for private companies to build and operate the networks. The Labor party also has a stated agenda to sell it off. Bizarre.
