You learn a lot about people (managers, founders, etc.) by how they handle their employees leaving the company. Looking over my career up to this point, the conversations I've had when leaving a company are ones that I still remember vividly, whereas I've forgotten a lot of other details about these places I worked for years. I think back fondly about the managers that genuinely wished me well at those exciting but scary junctions, even if I had my frustrations with them while I worked there. And if I'm being honest I still hold grudges against the ones that tried to make me feel bad and acted like I was betraying them for taking another job that I felt was the right decision for me at the time. Even from a purely self-interest perspective, it seems to me that it's in every manager's interest not to try to guilt employees that are leaving or talk negatively about them. It's the last chance you have to leave a good impression, it costs you nothing at that point, and you never know when you may cross paths again, or the employee that left may be friends with someone you want to hire in the future and warn them not to join you, etc.
