Well, that's the ideal. In practice, deployed FOSS code (which can always be
modified in-house, according to the free software definition), sometimes tends
to divert from the mainline code and be . Some examples:
1. Back when I administered the linux.org.il and iglu.org.il E-mail domains, I
was requested from the administrator of the Linux-IL mailing list at
cs.huji.ac.il to remove the linux...@linux.org.il and linux...@iglu.org.il
aliases, because they had problems dealing with them there due to the highly
customised setup on cs.huji.ac.il. It was all FOSS, but they had many custom
modifications and were afraid to upgrade.
2. whatsup.org.il's codebase is based on an old version of PostNuke, with some
adaptations to support Hebrew, which were not accepted because they planned to
do it properly using CSS, and since then has garnered many fixes and
workarounds to security problems. Since then PostNuke seems to have been
abandoned.
3. I know there are many companies out there who have still standardised on
using perl-5.6.1 because they are afraid to upgrade to a more recent Perl
version (there have already been the stable 5.8.x, 5.10.x, and 5.12.x
releases) because something might break. Now, perl-5.6.x is still open source
and someone can maintain it, but the world has moved on.
-------------
So there is still a risk of people writing inhouse changes for open-source
code and not propagating it for public consumption with open-source code. So
that does not make an availability of source code for in-house modification
"crapware" and we might as well call everything that's not 100% FOSS
"crapware" too. Furthermore, calling it "crapware" is not indicative of why
this is the case.
