"Don't bite the hand which feeds you" is a common phrase for what you described.

In my experience (20yr) good managers don't need any feedback. They were good because of clear communication as to what both parties expected of each other. Bad managers rarely listen to feedback and few make changes.

At my current role I'm thankful for the high level of autonomy received and being shielded from anything not relevant to my primary tasks.

I'm constantly asked to do "side quests" for others due to being a subject matter expert in several things (relative to my colleagues).

Every request gets the same answer - if my line manager agrees to it then I shall help - provided it does not get in the way of my primary tasks.

IMHO unless you own the company, your number one customer should always be your line manager.
