a) zeteo doesn't seem to be saying it is "good". b) The statement that something is "misleading" is a tense that indicates some kind of objective truth, potentially even an intention; this objectivity is certainly the case once the word "wrong" is used: "wrong" implies a rather strong statement about the map. zateo is thereby providing the context to understand that the map has a purpose, and what that purpose is; I am not certain why your response seems to take offense at that. If you are willing to state something is "wrong" if you are using it incorrectly, then all attempts to demonstrate any form of information ever are "wrong".
