Dry read, so I will sum up the best parts. :)
"the RySG is acutely aware of the need to focus on reducing the costs for registrants and end users"
"how could it [registry] reasonably be expected to compete on price with legacy TLDs?"
"operators believe ICANN fees have hampered their success and put them at a competitive disadvantage"
