What frustrates me most about people are hell bent on painting a wildly successful company in the worst light possible is that doing so has very serious negative implications for equality and opportunity for women and other groups that are under-represented in tech. Let me explain why.
Spending several years at a unicorn startup opens up so many opportunities. Look at early employees from Fairchild, Paypal, Facebook, Google, Microsoft, etc. These companies minted many many millionaires and gave them tons of valuable experience to go out and start their own companies after they left. When you so aggressively bad mouth the culture of a rising unicorn such that you discourage certain groups from even applying to work there, you have deprived those people of an opportunity to be on a rocket ship. You're perpetuating the very problem you're railing against.
My colleagues in the LadyEng group here at Uber have on many occasions lamented how hard a time they have recruiting other women to join the company because of the reputation in the media. The company culture has been so maligned by those with an agenda that even the women engineers here have a difficult time convincing other women to join.
If you really want people who are under-represented in tech to succeed, you should encourage them and support them in joining every rising unicorn that exists and will ever exist regardless of how that culture is perceived, because four years after joining they will have the money, experience and connections to create their own companies and perpetuate a virtuous cycle.
If you agree with this message please spread it because so few people realize how they are contributing to a self-fulfilling prophecy that hurts the cause they claim to champion.
