Usually government data is CC0 or public domain while OSM is not (maybe Germany is different?), so I thought they'd be allergic to OSM's licensing. OSM actually has a lot of problems ingesting data b/c a lot of map data can't be relicensed under their license.
Ironically.. you can't contribute map data that requires attribution to OSM... even though they require attribution..
It's a great project.. but I think they really messed up the licensing in a misguided effort to make the project viral. Maybe trying to emulate Wikipedia. But text and map data are just fundamentally very different. It's really unfortunate. I hope an alternative emerged eventually
