Thank you for the information! I’m going to investigate this.
I downloaded an original release of C locfit from
http://web.archive.org/web/20070616194305/http://cm.bell-labs.com/cm/ms/departments/sia/project/locfit/dist/locfit.tgz
and compared it to the copy in the Cufflinks repository at commit
d402b182fabd9a831ccb4173e3cb3a2d2dd2e75e (May 2011).
After copying a couple of files from src-c to src they do seem rather
similar, but with about a thousand lines worth of differences (excluding
whitespace changes). However, it doesn’t look like the code is based on
any of the GPL versions on CRAN[1], because the archives there do not
contain certain files (such as “ar_funs.c”).
If we could be reasonably sure that the code is a derivative of the
GPL’d locfit code from CRAN we essentially deal with a GPL violation,
and not a case of non-free software.
I’ll review this problem and will remove cufflinks by the end of this if
we come to the conclusion that it cannot be considered free.
