So much that. No one likes "drive-by advice" - if you want something to be fixed, there should be a person responsible for that. Maybe it's you doing all the work, or you convincing management, or management who is asking for an advice... But if you are just saying "we should fix FOO by doing this and that" with no plans as to whom those "we" are, it's only annoying.
