To give my extremely opinionated opinion: because science, politics, and philosophy haven't advanced past the assumptions that made cyberpunk look like a plausible vision of the future. And you can't necessarily just solve this "politically" with "activist scifi". You have to actually figure out which scientific and philosophical foundation-stones of our present social and technological orders are false assumptions, and figure out how to open them to question and speculation. Then you have to tell an interesting story about it all! (I often find that many of the people trying to "critique" our social order haven't taken that essential step of asking what the counterfactuals are to the false assumptions they critique. They think just by criticizing, you open some vast untapped field of techno-social possibilities. Nah, once you've grabbed the steering wheel, you still need to have somewhere to steer towards, a map of how to get there, and a map of why you want to go there.)
