   In case of the large US telcos my take on this is that they are after profit   
   optimization and are trying to invest as less money as possible. Since those   
   telcos have monopolies in most US regions they don't upgrade their networks to   
   make customers happy and provide faster internet access. They will invest only   
   when forced by a competitor. A few days ago New York state voted to throw   
   Charter out of the state for not delivering and lying after their merger with   
   Time Warner. AFAIK this is one of the very rare cases of an US state taking   
   action against a big telco. Back to IPv6. Rolling out IPv6 would require an   
   investment (man power, software, hardware), something the big telcos want to   
   avoid. Their customer service sucks already and a sudden increase of service   
   calls by customers about an IPv6 migration would become a nightmare. As long   
   as it works and makes money there's no reason to spend money for IPv6. And   
   this not just true for the large US telcos but also for tons of other   
   companies.
