The cyberpunk reality will be computer users finding any way they can to keep their PCs running on an undernet disconnected but in parallel from the CorpGov web. The latter where you are tracked, monitored, monetized, ruled, caged, where ypu own nothing but the CorpGov owns you. The former an illegal hoard of history, media, software, 3d printing, and information disallowed on the main web.

No flying cars, no cyberpunk body parts, just people trying to keep from being controlled.
