But Debian distributes OpenMotif under this license, next to non-free
software for which sources are not available. So clearly DFSG#9 did
not apply in Debian's view, otherwise OpenMotif would be
undistributable (then and now).

So what I find particularly puzzling is that this license is a bit
like the GPL (version 2) without a system library exception, and at
least Debian pretended that the system library exception was not an
option for the distribution. (According to that analysis it's only
something prioprietary operating systems coudl exercise historically,
due to the clearly separate vendors and distribution channels.)
Is it necessary that an open source license must allow porting to
proprietary systems? I don't think so today. But based on what I
found out about the OpenMotif license, people actually thought that
back then. This surprises me. Has this changed?
