TomTom joins OpenStreetMap Foundation as first platinum member (tomtom.com)

Cool. I didn't know TomTom was using OSM maps.

They involuntarily paid Microsoft some licence fees for the FAT32 file system way back when. This OSM contribution is voluntary.

I'm not sure what part or proportion of TomTom's services used by Microsoft either contain or rely on OSM data:
