Neil, I don’t “mistakenly assume” anything. If anyone "mistakenly assumes" something it is most likely as a result of your content-free emails, where teasing back layers of defensive ego-preening in order to obtain data germane to the subject matter at hand is an arduous chore.
What you seem to be saying is ‘these US providers have a larger profit margin and they have wasted this money on IPv6 deployment’. I find it hard to believe they would do this at such detriment of shareholder value. Are you realistically saying Comcast rolled out v6 to as many customers as BT has broadband subscribers (~6m), without a business case for doing so? OK, let’s exclude the US then. Those Americans well known for their callous disregard of profit anyway. DTAG has 26% deployment. Free has 39%. Swisscom 27%. [1] Why are DT or Swisscom doing this where BT isn’t? Is it really the case of Neil McRae standing up and shouting about the emperor’s new clothes? Or is there another factor at play here?
