My understanding is that AnonC is upset at Ars not taking the mature approach by allowing this to become a learning moment for the employee and using it to double down and confirm their stance on AI generated content. There's strength in maturity. But I am doing some reading between the lines, and I'm possibly reading a bit too much into "There’s something to be said about the value of owning up to issues"

Reminds me of a story I was told as an intern deploying infra changes to prod for the first time. Some guy had accidentally caused hours of downtime, and was expecting to be fired, only for his boss to say "Those hours of downtime is the price we pay to train our staff (you) to be careful. If we fire you, we throw the investment out the window"
