Hi, The issue with Open Sans font is different as it is a binary not a source file. It's Apache licensed but not obviously so. Most Apache licences software have source headers so you know how they were licensed, but a binary font file doesn't have a source header that's easily readable (the metedata in the binary may include the license information), so that pointer in LICENSE is just making the licensing clear. It's not actually legally required by the Apache license.
Thanks, Justin
