It's not gendered. A reporter discussed supposed sexism and misogyny at a company. The man is frustrated because it's probably untrue, but we don't have a clear picture because the press has been sensationalizing anything anti-Uber for a while now, and no credible evidence is ever presented.
That doesn't make his response or anything about it gendered. It doesn't matter who slanders, it's frustrating when it happens, and joking about digging up dirt to do the exact same thing back to a journalist so they know what it feels like is tantamount to wishing an abusive person would some day get to know what being on the receiving end of that feels like.
Also, you should really check your sources about harassment on the internet. Prominent men are harassed more often and more violently than prominent women. It's a recently constructed myth that's been hyped up by the media over the past few months that the internet is an especially hostile place for women.
