You seem to have a different opinion on this as the debian-legal people
who negotiated with the LaTeX project and together developped the LPPL
version 1.3. In this version, the requirement to change file names (or
LaTeX package names) was dropped, probably because it was regarded as
"too non-free", whereas it was decided that any changed version should
indicate that it was changed in the version string that is (or to some
degree only will be) part of the API.
Hmm. I claim that it is a mistake for Debian to consider something free
if it requires binary incompatibility to distribute a modified version.
Version strings are a funny edge-case, where if they're normally just
human-readable information with no programmatic effect I can live with it,
but when it becomes common to programmatically read them and behave
differently, then it's part of the API and must be modifiable (or not)
It's possible that Debian made a mistake if that's what LaTeX does with
these strings. Wouldn't be the first time.
It seems a clear test: if I can't distribute a changed version that
can be dropped into a system without changing other software,
it ain't free.
You can never distribute a bugfixed version of a font with the same name
(identifiers, ...) and, without changing other software, get the same
system behavior. That's not a question of freeness, it's a technical
No, the intent is to get DIFFERENT system behavior by changing the free
component, without changing other software or documents. That's the
freedom I'm worried about here. Though the ability to get the same
behavior is there too (perhaps a performance fix or other
result-compatible implementation change), it's just a special case of the
real freedom to make changes.
