That is like saying chemotherapy "can work against you" by showing a single skin cell died during the treatment; it isn't "working against you" unless you lose so many skin cells that the chance of killing the cancerous tumor is no longer "worth" the risk.
If you accept "single user got angry" then every single thing you can "can work against you", and the phrase is meaningless: some people hate the color blue, while some other people hate everything /but/ the color blue. Decisions need to be made "on the balance", not because there's one angry user.
