The point of her post is that Uber's HR is
complicit in this nightmare of a situation - actively working against her and other women. So to ask Uber HR to respond is a pathetic and cowardly attempt to shove the issue under the table.
Furthermore, saying "It's the first time this has come to my attention" is not a great response to a post which alleges that HR responds to sexual harassment claims by saying "this is the first time we've had a complaint against this guy".
