Care to amend your statement? I don't see any qualification about building software there.
Face it, the author was just searching for another reason to be mad at men in the software realm.
Also, I think the intended meaning of "tech bros" in the article is more nuanced. Charitably: naive, sophomorically idealistic SV tech entrepreneurs who rode the "information wants to be free" wave to a world where WhatsApp & FB Messenger are E2EE by default. Uncharitably: anyone not in author's idealogical tribe, particularly ideologically impure programmers who have turned to entrepreneurism. And Americans.
Good to know you don't think Yan or Runa's technical work is significant, though.
