To be fair, Shadowrun wasn't just "any sort of material that involves someone plugging a computer into their head". The terms cyberdeck, street samurai, megacorporation, IC(E), "jacking in", "the sprawl", razor girl and numerous others were directly lifted from Neuromancer. (And homages are still popping up in the material 20 years later.) Denying the connection is like denying BattleTech's connection to Robotech/Macross. William Gibson has never attempted to go all Harmony Gold on FASA/WizKids/Topps and that, in and of itself, earns my respect. Who cares if he likes it?
