I think it's only for purposes of estoppel.

Your lawyers are insane.  It's illegal to use this software in nuclear
power plants.  Yes, I suppose those laws could change.  But the fact
that it isn't designed for use in a nuke is *true*.  I don't see any
fee or other non-free requirement in silent and private
acknowledgement of true facts.

That's not provably true.  Sun, being the designer of the software,
can make unambiguously true statements about the design.

Similarly, you must acknowledge that I have written the word "Sun".

That's very far from true.

Because the acknowledgement is trivially proven to be true.  I agree
that if there's any question about the truth of the statement, it's
not free.  But for trivially true cases, I don't think it matters.
