They protested Closure selling the chocolate, so she was forced to just give us all of it.
Closure's intention was to sell it on the base, as in, to the other operators. The canine operators protested it because not only do fully human females with dog ears apparently completely share their internal physiology with actual dogs, for all the sense that makes, but they also couldn't just not buy something that would harm them for some reason.
All in all, I found the millionth "dog girls can't eat chocolate" joke really disappointing.
I assume some cat girls also protested since cats also can't properly digest chocolate.
Well, it only specifically named canine operators, suggesting they were specifically going for the stereotypical dogs and chocolate joke, but whether it's cats or dogs it's still silly to always apply normal animal logic to what are essentially humans with grafted on animal features.
