Hidden button is explicitly allowed on mobile devices by the draft: "In addition, mobile devices may have attribution after one interaction. Examples of one interaction include “one click,” such as an icon or link that opens a pop-up or new webpage, or a swipe, drag, pinch, etc."
from https://wiki.openstreetmap.org/wiki/Draft_Attribution_Guideline#Mobile_devices That would misleadingly claim that hidden button (used by Mapbox and FB and others on mobile devices) is acceptable and fulfills ODBL requirements. See https://raw.githubusercontent.com/matkoniecz/illegal-use-of-OpenStreetMap/master/Mapbox/Mapbox_attributes_itself_2019-12-30.png for an example in map with hidden button that would fulfill "mobile devices may have attribution after one interaction". This specific screenshot from mobile device (low budget smartphone) also demonstrates that there for full-screen maps there is enough space for a real attribution. Though something smaller than logo and "Mapbox" repeated three times would be also enough. To repeat: normal user will NOT click on weir "i" button. This is effectively not displaying attribution. -------- More info about that specific case at https://github.com/matkoniecz/illegal-use-of-OpenStreetMap/blob/master/Mapbox/Mapbox.md#mapbox-is-using-openstreetmap-data-illegally (yes Mapbox was notified, yes Mapbox ignored it).
