It looks like there is a fork, but I wonder what Mozilla or other apps/websites that depend on Twemoji will do. Go with the fork? Switch to OpenMoji? (Which is also only on v14 it seems.)
Emoji are (ostensibly) a commons overseen by the Unicode Consortium; it seems weird that so many took a dependency on Twemoji, which may now be backfiring.
