Folks,

1)
The GPL is included with the 6500 product literature, see

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/cfgnotes/78_10406.htm

This is a online copy of the documentation shipped with the card.  Thus
the claim "not mentioning the GPL anywhere... is indeed true" is difficult
to sustain.  There is no license requirement under the GPL to mention
"Linux" (which is a good thing, as the list of attributable products in a
Linux distro is huge).


2) The GPL does *not* require vendors to publish the source code to the
public.  It does require vendors to supply source code to purchasers of
product upon request.  That purchaser can then make the source code
public, if they choose and at their expense.

The documentation referred to above states:

> under the GNU Public License (listed below). If you would like to obtain

It seems to me that, in the absence of a report of a purchaser being
denied a copy of the source code upon a request, that there is no story
here and Cisco Systems have been correct in their behaviour[1].

I do which people wouldn't be so hasty in accusing people of violating the
GPL -- actually being a purchaser of the product would have been a good
start.  If this nonsense continues then companies will simply avoid the PR
issues and mandate that development use BSD licensed software over GPL
licensed software.  You can bet that the Cisco product manager for the
6500 IDS is being questioned closely about their choice of Linux rather
than FreeBSD.  They won;t be so eager to use Linux in the future, to the
detriment of us all.

Regards,
Glen

[1] With one tiny niggle.  A reference to the GPL should also appear in
the position where the license for the Cisco-developed software appears.  
Lots of embedded systems manufacturers don't meet this requirement of the
GPL.
