Great response. For the "retired" who stayed on, what sort of impact did their newfound attitudes have on things? Did they play a part in any of the major new products or improvements that came later?
To be balanced I've also seen them leave, basically to put to the powers that be a set of facts or demands that need to be true, only to have those same powers tell them it wasn't going to happen. Then they left. I try to pay a lot of attention to those sorts of events because depending on whose reasoning I find more credible it can inform my own thoughts about staying or leaving.
