Because there are things you can do with one that you can't do with
the other, and there are things you must do with one and you don't
need to do with the other.

eg

CCbySA says you must attribute where it came from, ODbl make no such
demand. So by following ODbl you break CCbySA..... and the law is
about black and white not shades of grey.
