If there were source-only-packages (i.e. no pre-built binaries), there would be no licencing-problems. Because of this, Gentoo can provide (source-)packages without violating any licences[1].
Also, Canonical might want to spend some money on this issue as Oracle (former: SUN) did to prove whether there is a licence violation in distributing binaries or not. See #7.
