@danderson @evana This is the likely explanation. We did a similar thing for infotainment at an auto company I worked for: we listed the license of everything that was built in Yocto, but some of those (like GCC, bison, meson, autotools, and other build tools) are never shipped in the image, so technically we may not have needed to list them. The source code tarball you can request under the GPL written offer clause also contains those (even if they're not GPL).
