The original module `github.com/xi2/xz/` is in the Public Domain but
does not explicitly specify a license. The module has not been updated
since 2017.
The fork at `github.com/therootcompany/xz` simply adds a Creative
Commons CC0 1.0 Universal (CC0-1.0) license declaration for Public
Domain use. However, this license has been disallowed by Fedora since
2022, as announced in the [Fedora Legal
thread](https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/thread/RRYM3CLYJYW64VSQIXY6IF3TCDZGS6LM/#EO4JUQRG4GDLRHJHJBUZDR2RHMXNU5HT), and the restriction also applies to RHEL and related distributions.
The module at `github.com/mikelolasagasti/xz` is a fork of `xi2/xz`, but
declares the BSD Zero Clause License (0BSD) instead. This aligns with
the licensing of the upstream source from which `xi2/xz` originally
derives, which has moved from [Public Domain to 0BSD for recent
updates](https://tukaani.org/xz/embedded.html#_licensing).

By setting the buildtags "no_lzo" and/or "no_lzma",
one can drop the library dependency on lzo and lzma.
The same could be done for xz as well, but there are
still lots of archives using xz compression out there.
