Looking through, the first thing that I noticed is the number of domains rejected by Australia, looking through the PDFs the reasons all seem valid, it's just strange that Australia is the one rejecting them.
I'm heavily against the new gTLDs because I don't see why private entities should own generic words. '.com' is not a generic word. '.book' is. I don't think the payoff is worth any of the multitude of problems.
-Argentina and Chile object to Patagonia Inc's attempt at .patagonia
-India objects to .bible
-Nigeria objects to Delta Airlines attempt at .delta
-China objects to .shangrila from some hotel chain by the same name
-Australia objects to most everything else including .sucks
It's important to note that this isn't because it offends them, but because whoever holds it can basically print cash once brands start realizing they need to register (brand).sucks before anyone else does.
1) Company X does not appear to specify sufficient mechanisms to allow communities to protect their names and reputations from misuse at the second level, except through defensive registrations.
or
2) Company X is proposing to exclude any other entities, including potential competitors, from using the TLD.
Restricting common generic strings for the exclusive use of a single entity could have unintended consequences, including a negative impact on competition.
