Yep. I once worked at a place that leveraged PII for profit. I won't work at a place like that again.

But I wouldn't hold working at Facebook against anyone, unless they knew and worked directly on monetizing PII and didn't see problems with it. That's for other reasons -- there are certain things you can't engineer without having a really good idea how, where, and why it'll be used. I don't want an engineer that is blindly solving technical problems.
