To most people, the name Telecom is about landlines
It will never be anything else irrespective of what moniker you give it. NZPO / Telecom / Chorus / Spark / Skinny will not change the lousy service you delivered over the years. And continue to deliver.
When you can get ADSL on copper or fibre past my door, only 6KM rural from a DSLAM, then I might believe your spin. Till then I will never directly give Telecom-Chorus another cent.
