Thanks, this is a trivial thing IMHO. Worker violates working agreement, news at 11. All the other fluff is just yellow journalism. He uses GPt? Yawn... he publishes mainly as co-author? That's completely normal in academia, particularly for high ranking professors. Wait until people discover that in several places in Germany, Proffesors delegate most of the PhD supervising tasks to lowly post-docs.
It's just layman peeking at the Academia world and getting mad at a cloud.
