I don't mean to cherrypick, but to address your main point: I did not leave my last job because of my boss, to the contrary, he was one of the most motivational/mentor figures I'd ever had, bar none. (To the point that I actually really regret leaving.)

I left because I was told that due to it being academia, I was hard capped at essentially <2% yearly raises unless I swapped jobs out and back, and holding myself to a hilariously low academic salary this early in my career was going to really set me back financially in the long run.
