It seems their argument is that the New TLDs (the program they created that allowed the creation of .donut and .pepsi and such) doesn't have these limits, and it's unfair to the companies running the "old" TLDs that they do.

Which is a terrible argument, not just because an answer could be "then impose limits on new TLDs", but also because those new TLDs are new products which those companies have to pay for, market, etc, whereas the companies running the old TLDs are just maintaining something that was created by the public.
