I don't know if it applies for majority of people but in my social circle we treat palantir with stigma and actively tell people not to work for them. So, is it really mean to tell that? What can normal people do ? Telling people not work will help society in long run and also signals advertisers, consumers not to use their product:) It is similar to why USA has banned companies to not use any kind of cotton produced from xiangxinag although they might not personally know if that company is in mortgage and can afford to survive if they don't use cotton from china?

If you work for Facebook then you have in-demand skills that will command a high salary elsewhere. Facebook is a highly unethical company and people should avoid working for them, your imaginative story notwithstanding.
