Earlier quoted context omitted.
No, he coerced them into it - if you have a position of power, and you say "have sex with me", effectively in exchange for your treatment/employment in the company - I can't recall if Rubin was the burning man "sex or no job" guy, or that was another - that is sex discrimination and/or harassment. I doubt Rubin would have had the same behaviour with male subordinates, so that's a difference in treatment based on gend…
The burning man guy is another guy (who still works at Google afaik). This Rubin guy was no doubt a creep. From the NYT article: "The suit included a screenshot of an August 2015 email Mr. Rubin sent to one woman. “You will be happy being taken care of,” he wrote. “Being owned is kinda like you are my property, and I can loan you to other people.”" Yikes!
As others have already pointed out, any relationship with an employee in that kind of environment is exploitative by nature.
