Shouldn’t the picture in the article that is labeled system map be the official metro map that is used by WMATA? 2600:4040:B67A:CD00:E875:AC66:9150:A63C ( talk) 22:30, 9 July 2023 (UTC) reply

That might be ideal, but the official map is copyrighted, non-free content. Under the non-free content guideline, non-free content can only be used on Wikipedia when a stringent set of criteria are met. Specifically, use of the official map would not meet criterion 1 ("No free equivalent"), since a free equivalent for the map has been created. We use that free equivalent instead, since it serves the same purpose while also allowing free reuse under a Creative Commons license. PlanetJuice ( talk • contribs) 23:02, 9 July 2023 (UTC) reply

It is illegal to use official transit maps in transit articles on Wikipedia becuz they are copyrighted. For example: In the articles Metropolitan Atlanta Rapid Transit Authority and Mass Rapid Transit (Singapore)#Network and infrastructure, you will see fan-made system maps and not the official ones.
