"They?" Who do you think "they" are? There are 4 abusive hosts, and the 
suggested blocks potentially cover over 128 million hosts. Are you 
suggesting that you know as fact, that because 4 hosts aren't following 
the rules, none of the other 128 million are, either?

You're probably right that hosts in AsiaPAC don't need NTP service from 
USNO. But, the recommendation was made to the audience at large, which 
can't be assumed to only represent a single region.
