I know that in Google My Maps, I can click the folder icon and select Export to KML to download a KML file.
However, is it possible that, given the URL of someone's My Map, I can go in and get the KML out of it? I've read an answer that you can add the
output=kml querystring to a URL, but that looks like something that used to work in old maps, but is no longer supported.
So, is there any way to currently do this with the current version of Google Maps?
