Here the government made a clear decision that ADSL and GSM should be open to competition and separate from the old monopolies. So one can choose the ADSL operator. The local company then gets a rent for the line from the ADSL provider. As for cable I think you need to be hooked to the cable TV which means that you get all your TV from it. It costs nothing extra to the individual apartment owner (though one of course pays it as part of the monthly payment of pays that covers all the general expenses). One does not have to have pay-TV to get cable modem. As I have understood in the U.S. it is for the individual residents to decide to join or not join the cable. Here it is done at building basis. Individual residents can then choose whether to get pay-TV as extra.
