That's true of most SF. SF is primarily political, and has been since at least the late 50s. Although there is hard SF where the science leads, it's rarer - and less interesting - than SF which uses imaginary technologies to set a scene for political and social questions.
IMO Le Guin and someone like Heinlein were two sides of the same strand of SF. They're both moralists rather than technical speculators, and in their own way they have a didactic streak where the morality is confidently presented but rather heavy-handed.
Although The Dispossessed is politically ambiguous, it's not ambiguous in an unfathomable, mysterious, or unconfident way. Neither is something like Dune, or the Culture novels. Or even Asimov's Foundation.
Part of the appeal of these authors is that they seem quite sure of their political and anthropological sophistication. While their characters may struggle, there's never a sense the authors feel they could be completely blindsided by human or alien anthropology, or steamrollered by non-human influences which are incomprehensible and impossible to deal with.
