I think people are underestimatig the psychological impact of failing to act on fraud in your research. Once you've learned that you're a fraud and what you're doing is bullshit, it would be soul crushing to go to work every day.
I have a feeling that non-academics on the Internet have an overly bleak view of the ethics in acamedia. I don't know why, but several online influencers really like to peddle the idea that we're all corrupt.
