Rewriting the GNU Coreutils in Rust

While both licenses have explicit patent grants, they differ greatly in scope.

ASLv2's patent clauses kick in only for _contributions_ to the software (ie "by contributing, you're granting a license for all patents you have that relate to the software") , but GPLv3's patent clauses go considerably further, applying even if you merely redistribute unmodified 3rd party software covered by a patent you hold or have licensed.
