What do people expect?
Everyone was pointing out to NBN Co. when it was all first started, that Telstra's reporting was on line quality for voice, so it didn't matter how much crackling or hissing you heard, if you could hear a voice on the line, you had a working service.
Whereas much better line quality was needed for data, hence why replacing the aging copper with fiber as part of the original FTTP roll out, was the better option in the long run.
