Have you tried that? What have you got? There is some interesting thinking there going on. Apple releases lame maps and everyone goes "Android is superior there", but when you cannot get for the source of this app for android then we get "Maps are not really Android".

The issue with Maps is the data. Open source is about code, not data.

Yes, then what about the source code for google maps, gmail and google play? Are they open source? Do you get them doing your git checkout?

My point is that the value of Google Maps is not in the interface, it's in the data. Apple Maps has the interface down ― that's the easy part.

Google has never claimed that apps specific to its services were part of Android to begin with, so your point is moot.

Dumping your source code into a repository after release may technically be open source, but it isn't in the spirit of community developed open source.
