While the goblinoids can be used as a coherent whole, there is definitely a hierarchy amongst them, with goblins being at the bottom of the totem pole, followed by hobgoblins, norkers, and finally bugbears at the top of the list. The "Humanoid Racial Preferences Table" from p. 106 of the original DMG is illustrative of the dynamic:
Hobgoblins (and presumably norkers) tolerate bugbears, bully goblins, and hate hobgoblins belonging to other tribes.
Goblins have goodwill towards bugbears, prefer the company of other goblins, and tolerate the bullying of the hobgoblins.
Given the fact that the non-goblinoid races never seem to get along with the goblinoid races (with the exception of goblins and kobolds, who doubtless get along because they're both on the bottom end of the totem pole, strength-wise), a dynamic of goblinoids vs. the other humanoids does seem to be implied.
