The assumption seems to be that companies culture is driving women away. Is that even true, as in, are there really hundreds of thousands of female software developers in waiting who would jump at a job at a company with the appropriate culture? It seems very unlikely to me - more likely, the pipeline dries out long before the hiring stage. That some companies with great effort manage to compete over the few female developers on the market doesn't prove every company could hire lots of female developers if only they changed their culture. To be honest, personally, even if there were those hundreds of thousands of female developers supposedly driven away by bro culture, I would still maintain that people should have a right to create companies they enjoy working in. If some people want to work in T-Shirts and get drunk every night, it is their right to do so (if they can earn the money to sustain it). Luckily not all companies are the same, so that people can apply to companies that suit their tastes. If it weren't so, there wouldn't even be a need for hiring or job seeking to begin with. People could just apply to the next best company and be hired, likewise, companies could hire the next best applicant - because there would be no such issues as cultural fit or whatever. Not very realistic (source: I am not friends with everybody and not everybody is friends with me).
