The fact that she did end up setting herself apart is what's remarkable. For every one of her who was able to self-reflect, become horrified of the ethics of what she was doing, and took the hard steps of stopping and breaking away, how many current and former Meta employees don't do this reflection and remain contributors to the problem? 1:100? 1:1,000? 1:10,000?
Did you read the book? Because that's not the story, she way too many opportunities to do that, yet didn't. Only after she stopped getting paid, she did an "expose".
I hate facebook more than the next guy but this person just helped Facebook to accomplish usual evil things, and only stopped once she cannot profit. I'm pretty sure she didn't start that way or maybe even saw it that way, but objectively (in her own narrative, if you only take actions and ignore her own emotional justifications) that's what happened.
She didn’t set herself apart. She was fired. She was forced apart.
That’s the issue here. Is this someone who found their morals or someone who found a stick with which to strike back at those who hurt her?
One of those doesn’t require her to change at all.
A few years ago I had a date with a backend engineer at Meta.
I asked if they'd ever considered the societal implications of the work they did. They said "Oh wow I've never even thought about it". Probably a solid hire from Meta's perspective.
