is the goal screen protection for OLED displays? then yes, why not. But does this then also hide the copyright text? It should I would say.
Are there map apps / websites that hide the attribution text?
(it is a prerequisite for the use of their maps)
Map scale in some implementations appears when needed.
Like when touching the screen to zoom in / out.
As option, like the compass and the other buttons on screen.
I do not know if that helps or if that has any legal relevance, but OpenLayers library has a feature to make the attribution collapsible.
https://openlayers.org/en/latest/apidoc/module-ol_control_Attribution-Attribution.html
I used that in former versions of gpxshaping (bottom right of the map):
Test route in old version 210715
Screen protection could be reached also by alternating positions of attribution (e.g. each 2min, left->middle->right bottom, perhaps stepwise pixel by pixel).
But - of course - that might have a negative impact on the “look”.
From my point of view I would prefer alternating positions (I am thinking about buying a mobile phone with OLED display) - the attribution is small and does not disturb.
These features exist but they are mostly considered to be not compatible with the OSM license. Copyright and License | OpenStreetMap
There are many discussions about this. For openlayers there is for example this discussion: Contradiction between collapsible docs and OSM source · Issue #8621 · openlayers/openlayers · GitHub
OSM is a bit loosely with their requirement.
For a browsable electronic map, the credit should appear in the corner of the map.
Some people like to argue that a collapsing element in the corner is doing that. Others argue that this is not the intention of the license.
Thanks for the hint - I will set collapsible=false in the provided old versions (backup).
In versions of October 2021 and newer the attribution (depending in used map type) is shown not collapsible in any case.
