Leaving morality aside for a moment, I wonder what the attribution requirement actually is in that situation. Say you make an Android app that has no built-in tile sources but if you enter an URL in some text box it will try to load tiles from there.<br>
<br>
Does CC-BY-SA require that the application programmer somehow cleverly finds out that the user has entered the OSM tile server, that this tile server serves CC-BY-SA tiles, and that the attribution is so-and-so? Probably not, which means that as long as you don't explicitly support OSM you don't need attribution, right?</blockquote>
