It's about being empathetic and compassionate. Even if you are not like everybody else, it's a good exercise to imagine how other people like to receive information.

If I received an item that is fully functional, but I wasn't told that it's in questionable cosmetic condition when it in fact is, I'd be upset, and I would be asking for a refund. I'd be doing so in a negative tone of voice, because I have to go from a high level of anticipation and excitement, to disappointment and the hassle of sending it back and start looking again.
