I don't think that Palantir being a public company would necessarily give the kind of insight into what they do to satisfy our curiosity. As far as I understand, Palantir could be very financially transparent while still keeping mum about who their clients are and what they are doing for them.

I agree with you on the whole, but Enron was pre Sarbanes-Oxley which initiated a raft of reporting requirements on companies, so Enron is often a poor comparison to the present day.
