Google and Apple are both free to use OSM data (which is of course copyrighted). But the don't want to because they can't abide by the license terms.

Apple does use OSM in some countries like Ukraine IIRC. They are free to do so. https://wiki.osmfoundation.org/wiki/Licence/Community_Guidel...

Although their attribution is leaning on the minimalist side.

Turn by turn navigation in Apple Maps in Denmark is OSM based. (If I remember the talk from the Apple engineer at State of the Map 2018)
