There isn't one stereotype from that era for good reason. There are a bunch of disparate ones. There were and are cyber-hippies in large very progressive groups. They are the ones being talked to here. Some of them are the reason that these tech culture problems are recognized as important problems. So yes, the stereotype acts as a stereotype: taking on only the set of features needed to support an argument. So don't use or think in terms of "nerds", as that's too coarse to be useful or to tell you anything. Tech is an industry with various subcultures. The OP didn't use the stereotype anyway.
