I definitely agree this can happen, and I've worked for a company where what you described rings all too true. However, I joined Palantir last year, and I genuinely don't see any evidence of the same kind of dysfunctional power dynamics.

During the interview process I asked a number of questions about ethics and transparency, and the interviewers responded positively and encouraged me to continue asking hard questions, which gave an impression it's a trait they valued.

After joining, I haven't seen any evidence of people fearing to express a dissenting opinion about either technical or ethical subjects. And I've personally witnessed a consistently high level of professionalism and respect, including respect and empathy for the protesters who want Palantir to sever all ties with ICE.

I don't think Palantir continues to work with HSI due to a lack of questioning, on the contrary, I think what's happened is that deeply questioning the ethical and practical implications of continuing or discontinuing contracts with HSI doesn't lead to such a clear-cut, black and white answer about what the right thing to do is.
