I'm also wondering how that recommendation (requirement?) made it onto the "copyright" page. Based on existing websites and applications using OSM data, this is not at all an universally accepted standard for attribution. In the case of apps/sites intended for mobile usage, it is rare to see attribution in the corner due to screen space constraints. But even for desktop applications, about boxes aren't uncommon either. The only subset of "browsable electronic maps" where this approach to attribution dominates are slippymaps on websites for desktop usage. The popular slippymap frameworks probably contribute to this because they place it in a corner by default. But even there you will find exceptions among popular websites within the OSM community that have existed for years. This is usually the case where multiple sources are used to create the map, making it impractical to list all of them directly on the map. To summarize, the "corner attribution" is clearly not the best choice at least in the following cases: * on mobile devices with small screens * when combining several sources that each ask for attribution * with technical limitations (e.g. no hyperlinks in drawing area). So my suggestion is to remove or rephrase that section of the copyright page. It should be allowed to place attribution in a dialog (such as the standard "about box" user interface convention for desktop apps) or a separate "license"/"sources"/"about" page - which of course must be directly and easily accessible from the site displaying the map.
