What is the issue? It is fiction, it doesn't pretend to represent reality in any way. It is more about badass cyborgs than it is about fear mongering.
But it is dystopian fiction, a genre that has its roots in real society problems turned up to eleven. It is not realistic, but it tends to feel real because of how psychology works, the negativity bias in particular. Same idea with 1984, pure fiction, looks nowhere near modern society, but people will go out of their way to find similarities.
GP sounds like someone complaining about gore/horror being written and filmed by people who never studied anatomy/physiology or sliced open cadavers. Accuracy is not the point of body horror, and fixating on it misses the point of the genre while patting oneself on the back. Same goes for Sociologists/romance novels and infosec folk/hacking scenes: remove your professional hat and enjoy the art for the fiction it is.
