I think the author was complicit and only complained once FB stopped paying her.
It was weird how the author claimed not to know how facebook targeted ads worked until 2016/2017 after she had made millions.
So you should never be allowed to comment on the behaviour of companies you worked for?
Though if she was complicit she's probably in a good position to expose it now things have changed.
Seems to be a common pattern, it's better than the alternative but nonetheless it's not the brag they think it's.
So what? If we need unscrupulous people to tell us what other unscrupulous people do, so what?
Literally anyone with the access to these people would be someone making bank. Do you think Cheryl Sandberg would bother to talk to a poor person?
That's kinda the nature of whistle-blowing. You're complicit, you have inside knowledge and THEN you choose to do the right thing. Snowden worked for the NSA before he exposed their lies about spying on US citizens, you think he did literally no work towards that end before blowing the whistle?
