I'm not entirely convinced of that attitude; plenty of science fiction in a cyberpunk setting have strong underlying messages, of e.g. personal identity, capitalism, privacy, overpopulation, sex work, drugs, classism, AI, environment / global warming, etc; some of the big names there would be (imo, I'm no expert and I can't think of much) Ghost in the Shell, Altered Carbon, The Matrix, some episodes of Love Death & Robots and even Black Mirror, to name a few.
