This looks like you've subtly dodged the complaint I raised by trying to insinuate that she doesn't have a right to express opinions aboht functions of Google she herself did not personally participate in. This leverages the information asymmetry in disclosure; we can't publicly discuss the bulk of her work and therefore you can suggest that there was none.
I find this to be no different from suggesting that she has no right to protest and therefore deserves to be run out. You're just trying to run the standard "she wasn't that important and therefore doesn't have credibility" playbook. Gross.
But despite the disingenuous argument, I'll accept it head on. I challenge the entire premise. I certainly can and do express opinions about my employer's involvement in weapons development and I am glad they are not doing it. I'd fight to avoid doing any more of it, and I'd be willing to resign over it. I don't work in AI, but my work supports any such system at Google and therefore I'd feel responsible to help prevent building killer robots in any capacity.
I, like many such employees, am both a shareholder and an employee in a company that claims to have an interest in a transparent and egalitarian corporate culture. This practice will naturally introduce friction between different parties and I expect us to work through them as fairly as possible. So I will not simply eject at the first sign of something I don't like. But if I feel that there is a line crossed while I was there strenuously objecting to that line and I haven't been given adequate reason to change my mind, I won't hesitate to resign.
I make these facts clear to folks when they hire me. If they don't like it, they shouldn't hire me. Hopefully you respect your own agency and intellect enough to give yourself similar license in your own life.
