Obviously, if regular employment is hostile to a woman who is interested in software, she would instead do software where she has more control over her employment terms. His outright dismissal just because he, a dude, notices other dudes encouraging women to apply to their company, does not address whether or not those dudes are good co-workers for women in the same way an incel may be desperate for women but that doesn't mean an incel is women-friendly!
Instead he concludes some bizarre logics: he tries to conclude some inherent quality to being a woman that explains this phenomenon vs being a man.
