That would suggest that in discussions on the history of technology, it is implied that there is some arbitrary threshold... But there's nothing arbitrary here, we know who invented the Internet. None of them where women. The argument that women could have contributed but didn't "because they were an oppressed group" is just an absurd couterfactual. Who knows what would have happened? You can say anything you want... Richard Spikes' contribution of turn signals... Richard Spikes invented the turn signal. Full stop. Saying he contributed to the invention of the automobile is as absurd as saying that Edison or Tesla contributed to the invention of the turn signal. No one would say that because the turn signal stands on it's own. Using your line of reasoning, Richard Spikes invented the turn signal with contributions from who knows how many women and other minorities. Or is it merely an acknowledgment of the fact that white men get the credit because they structured the industry to give it to them, by excluding everyone else? That doesn't mean women should get a historical "participation trophy" just for being somewhere and doing something in computing while the actual inventors where developing the Internet. It's insulting to them and women (and Al Gore...).
