In possible defense of this woman...
So initially, she's a woman brought on for a top leadership position to a problematic company. This is her chance to make some money and turn things around... And woman having top roles in business is a great thing. 100 years ago, that simply did not happen. Although there's still a fight for gay rights, trans rights, and the right of marginalized people, and there's still people being genocided and with no human rights, and people being tortured, that doesn't mean the struggle for woman's rights is over and that there's not some value to women taking top positions at large corporations.
And she made some progress on making that company less unappealing to advertisers, and did some good things...
AND THEN came the Elon Musk Hitler salute. And she probably had invested a lot of time and energy into the role, was being paid well, and was frustrated. Is she, as a woman in business, required to walk away from her efforts just because Elon Musk is a PR disaster and prejudiced person?
And then THIS finally happened. Her whole thing was just to be a businesswoman, be professional, and help make things profitable for this business unit, and this new AI change (which she almost certainly had nothing to do with and completely sucker punched her out of nowhere) completely undermined her.
So she did the smart thing and walked away. It was too much, it was undercutting her effort, she's moving on. Her last tweet was also very professional and corporate. She's a businesswoman.
Should she have left sooner? Should she have taken a stand against transphobia and some of the awful things on Xitter earlier? Yes, but also she had a boss, she had worked hard to get to where she was, and perhaps she wanted to make more money before exiting.
Does anyone know if she personally has done anything that indicates bigotry or prejudice towards trans people or Jewish people or anyone being genocided or tortured? I think her situation is somewhat understandable.
Even if we want to work toward a more egalitarian world in which all people have rights and are respected, woman will still be in organizations, most likely (if global warming doesn't kill us all), and so shouldn't woman be able to succeed?
