Where do you get that from? I thought those licences say that you
cannot remove the disclaimer when you redistribute the code, and you
must make recipients aware of the disclaimer:
"provided that you conspicuously and appropriately publish on each
copy an appropriate copyright notice and disclaimer of warranty" (GPL)
"when started running for such interactive use in the most ordinary
way, to print or display an announcement including an appropriate
copyright notice and a notice that there is no warranty" (GPL)
"Redistributions ... must reproduce ... the following disclaimer"
I have always assumed that the idea was that if the author didn't put
such conditions in the licence, and if someone redistributed the code
without the disclaimer to someone whose dog died as a result of using
the program, then the author might be found to be negligent. It seems
a bit far-fetched, but perhaps it makes sense in some jurisdictions,
and I can understand why it's worth being careful when the copyright
holder is an organisation with lots of money (such as MIT). When the
author is a private person and not a millionaire, there's probably not
much practical difference between a BSD-style licence and public
domain. Perhaps it is mostly just tradition that makes the former so
much more popular than the latter.
