Have you gone out of your way to make it clear you want this kind of feedback?

I've had managers who either consciously or otherwise had given me the impression that they're find with their management style and aren't really interested in changing it. That's fine and doesn't necessarily make them a bad manager, but going out of my way to provide "feedback" to them would have only harmed my career.

I've had a couple managers who explicitly told me on multiple occasions that they wanted feedback on their performance and if I thought they were doing anything wrong, inefficiently, stupid, etc., they wanted to know about it.

I've also had a couple in the middle, and for those it's much safer to just keep quiet. It's pretty high risk/low reward in that scenario.
