That’s Gwynne Shotwell, COO of SpaceX btw. Maybe the best that could happen to SpaceX. The other one is Shivon Zilis. What role does she have nowadays?
It certainly speaks to a level of professional conflict. If you have children with an employee it could very easily affect the way you treat that person in the workplace. It can easily undermine them in the eyes of co-workers.
She may well be perfectly happy with that but the OP was specifically holding her up as an example of Elon's track record with women in the workplace.
There are indications to the opposite. What you have pointed out is that he has hired two female executives across the dozens of individuals in his portfolio. Better than zero, I suppose.
I would give him and Linda the benefit of the doubt before jumping to any conclusions.
