Here's my attempt at a summary; corrections welcome:
- Up to 2018, the Unicode Fonts for Ancient Scripts (UFAS) project
released its fonts under terms that suggested a free license[1]:
- One of these fonts, Symbola, has an exhaustive coverage of Unicode
"symbol" characters, so exhaustive that we use it in our default
fontset for various "symbol subgroups"[2].
- In 2018, the license for UFAS has changed to the document I referenced
in my earlier message[3].
- Most GNU/Linux distributions reached the same conclusion: the terms of
this new license does not allow redistribution under any way, shape or
form[4]. Therefore, these distros now only ship the last free-license
version of Symbola.
- New versions of Unicode have come and gone since then; they have
introduced new blocks and new characters (cf. the initial bug report).
- Newer versions of Symbola have followed like clockwork to cover the
latest "symbol" characters.
- Unfortunately, these new versions fall under the new, non-free
license. IIUC this makes them unsuitable for Emacs's default fontset.
Distro developers have reached out to the UFAS developer (as recently as
two months ago for Gentoo[4]; see also Fedora thread linked earlier),
but they could not convince him to switch back to a free license.
[1] The terms have changed over the years; see for example:
