Dude gets fired for violating company policy, people have been fired for much less. Why is everyone getting their panties in a knot? Why isn't this post being flagged like all the other ones about the manifesto itself?
I know someone who left after 6 months for similar reasons, fortunately things didn't go as far for them as this poor man. I was warned off joining the company by that engineer and often think about how lucky I am to have dodged such a toxic place.
I had a couple of job offers, one was for Uber. I was super excited about the opportunity but I spoke with one of their engineers (former) and he warned me off accepting the offer - said it was a toxic, sexist workplace and said he would not recommend women to work there. Needless to say I declined.
