Hi Rhys, It is up to the package maintainers and one of their specific tasks to decide whether to forward an issue to upstream.
I have just found that you have documented the monoMMM_5.ttf to be licensed under GPL (version not specified) at https://gitlab.com/flightgear/fgdata/-/commit/436f67105a9e2ae450a395ca01ccea0c9049fb5a This part of the issue is a Debian-only one (document it properly in the copyright file). For the other mentioned files I have just created an upstream issue. Thanks, Bastian
