Madman with a Boxed Set
I can’t think of anything more punk than slaves escaping their bondage and fighting for their freedom and their lives. What could be more “the Man” than slave owners, slave masters, slave makers, and escaped-slave murdering cops?I'll be honest: I am not seeing this "fuck the man" attitude anywhere in Blade Runner or Neuromancer. The only punks in Neuromancer are the Panther Moderns, and they are explicitly called out as being nihilists whose movement will be gone tomorrow. Everybody in the rest of the novel does what they're told because they're being paid.
Blade Runner is about a guy who works for the man shooting down runaway slaves.
Neither work features anybody with a particularly political view, except for Riviera, and he spends his time making sure that his girlfriends go political, then turning them over to the secret police.
I think that you are heavily conflating the political aims of the punk movement with the surface description of cyberpunk, and warping most of the source material to fit that idea rather than allowing the works in question to stand for themselves.
This is why the distinction between cyberpunk characters and cyberpunk settings is important. And where the punk elements are expressed. Deckard is the Man and therefore not a punk until the end when he realizes that the replicants are human enough and decides to protect Rachel. The replicants are punk as fuck throughout.
