Regardless of your musings here, I can guarantee that nobody (i.e. very few) users will go through the effort of adding the attribution text to every screenshot they make to discuss things that are visible on an OSM map.
If this is going to be a problem for the OSMF, I suggest to put an appropriate copyright note at the footer of each page on this forum. But whether they find this necessary is for the OSMF to decide and execute.
