Anyone who has worked in mapping/GIS at a company that sells in China has seen this in action. The "display these islands larger" requests, the obfuscated coordinate system for geo-aligning maps, and other map content regulatory issues[1] all need to be dealt with if you want your map product available in the country. Not excusing it, but every company with maps there is required to do this, not just Apple.
