Managers -especially young ones- can be quite insecure. They don't want folks reporting to them that can call BS.
Basic human nature.
TBH, they have a point. I was a manager for many years, and know BS when I smell it. I had a management style that involved a lot of self-reflection and intimate feedback loops with my employees, but I also managed very experienced engineers that all knew more than I did, so treating them with respect, and listening to their counsel, became second nature. It wouldn't have bothered me a bit to have employees that used to be managers, as long as they were good engineers.
Not sure that most managers, these days, operate that way.
