I wasn't suggesting that, I was thinking of TSVN as a minor part in a
larger package of software
where attribution is still present. Considering how rich and mature TSVN
is I don't really see anyone
going off and creating something mind boggling new and then releasing it
under their own name without
the source. What feature would that be? It would probably be easy enough
to re implement without the
code for it anyway.

Both would be a disaster, also when a baby is born... It won't go back

As it turned out it was difficult to draw the borders what needed to be
under GPL and not. This analysis
process and the risks involved of you "guessed" wrong turned out to be
reason enough not to use GPLed
code for anything else but pure tools.

I think there is a significant difference between TSVN and e.g. Linux or
svn. TSVN to me is kind of mature
in that it pretty much does all it needs to do and is very much defined
by the library (svn) it wraps. Modifications
to it would probably be pretty specific, like I wrote above, limited to
configuration, packaging etc. I don't
see the acute need for assuring that such code is made public since it
would be of little to no value for the
community. The important stuff that really needs protection is what's
already written.
Linux or svn on the other side have a much greater potential for feature
addition that are not trivial and may
be very interesting for the public.

By demanding that companies make public their changes to the software
they may have to disclose sensitive
information such as hardcoded server names, specific work procedures
etc. that could be seen as a competitive
edge. Such disclosure would certainly mean TSVN won't be used.
