Don't be fooled, there's still money in what she's doing. Plus other forms of personal gain. I doubt this hurts her with reddit given their actions over the past few years and this positions her to be a hero to a very powerful and growing political movement.
Sheryl Sandberg's Lean In has sold 1.6 million copies, if she gets $1.50/book thats $2.4 million. Plus $50-100k for speaking engagements, plus seminars, other branding, revenue streams, etc. She's a billionaire so if she ends up making $10+ million through her activism that's no big deal, but it shows there's decent money to be made there.
"Professional activist" is a now career. Anita Sarkeesian's kickstarter to expose male privilege in video games brought in over $150k, originally it was for under $10k but over time she's been able to monetize her victimization in the sense that the more she's "victimized" the more her supporters give to her so she can continue fighting the power. Her non-profit brought in almost $400k during fourth-quarter of 2014 because of gamergate. (http://www.forbes.com/sites/erikkain/2015/01/24/anita-sarkee...) Her career hasn't been hurt by discrimination, it's been made by it.
It's like racism and the black community, it's really bad for most of them but then there are the Public Enemy's and Al Sharpton's who thrive on it. Is Al Sharpton a victim of racism? In a way, but he's also a major beneficiary of it. Is Pao a victim of gender discrimination? Maybe, but she's positioned to capitalize on it either way. Could she make more than the $400k severance package she was offered? I wouldn't doubt it. Will it make up for lost income? That's only a question if reddit let's her go, which doesn't look likely: http://fortune.com/2014/11/13/reddits-new-ceo-may-not-be-int...
