You may very well be right about Truenet having no influence on Spark's network investments, but as a consumer, how am I supposed to know? I'm not just going to take your word for it, due to your vested interest as an employee. In addition, you have a vested interest in weakening the position of Truenet and similar services, because in a world where govt funding for ISP monitoring lapsed due to lack of public interest, Spark's position as the incumbent would be strengthened. Interested consumers would have no actual data with which to counter Spark's marketing claims (for example, saying they had the fastest ISP network due to some internal study), likely leaving them unchallenged in the NZ techie world.
Please note that I'm not trying to ascribe any malice to your words at all - I honestly believe what you said is genuine. I'm just pointing out how your words are weakened by your personal interest in the subject.
Sorry, I'm getting a little off topic now.
