A while ago, I installed Emacs from the Ubuntu repositories, and have been using it occasionally. Recently, just for fun, I installed vrms, a tool designed to detect non-free software according to the Debian definitions. My system was relatively clean, with only a few packages flagged.
However, the package
emacs24-common-non-dfsg was among them. This seems a bit odd. As far as I know, Emacs was written by RMS himself, so this confuses me.
Are there indeed ethical issues connected to this package? If so, what are the recommended free replacements?
In the case there is no reason for this package to be flagged, what are possible causes for the flag?
