Not every feature in Android is designed to be monetised. Google develop Android with the intent that users will use their app store/click on Google provided ads. They can only do that if they are seen to be offering a competitive, feature full product. The cloud-based syncing of your phone configuration is one of those features.
Having worked in various large organisations (including ones which are definitely part of the military-industrial complex) I can say wholeheartedly that there is no grand conspiracy. Most people, wherever they work, want to produce the best product they can.
