It is the other way around. Google Maps is now getting GTFS data directly from Prasarana/Rapid Bus including realtime bus arrival data. But not all data that Google mark as RapidKL’s actually came from Rapid Bus.

Similar for Moovit. They now get directly from Prasarana/Rapid Bus its GTFS data too, however they do post processing so some things are changed/streamlined (duplicate bus stops name etc).

OSM mappers can certainly request the same data in GTFS format from Rapid Bus for updating into OSM. :wink:
