Not to discourage usage of OSM at all, but you can absolutely download offline maps on mobile with Google Maps, they’ve just hidden it a bit. If you tap your account icon in the upper right, a menu pops up that includes offline maps, and it’ll let you select boundaries to download.
Is this a community, or is this a circlejerk? I don’t think categorizing beginners who don’t know where to start as leeches creates the kind of environment people of all knowledge levels want to spend time in. You don’t personally have to educate them, but telling them off for asking is pretty rude.
