> c.) that the cheaters clearly are skilled after all because of all their success, as evidenced by being promoted, so it's ok.

Quite possibly that some commentators think that way, but I doubt that cheaters suddenly stop cheating after the interview, particularly not if it worked out so well for them. I rather think they'll continue their path of alternative facts; blaming others for failures, mis-attributing successes, mis-charecterizing their contributions, lying, gas-lighting, bullying and even squeezing their colleagues out of their job. There might be work environments where this is a net positive for the organization, but I can't think of one right now.
