Here is the clause in question:

   6.  If you base research on SWI-Prolog and publish on  this  research,
 you   must   include  appropriate  acknowledgements  and  references  to
 SWI-Prolog in your publication.

Only when you publish academic results that *you* based on SWI-Prolog do
you have to acknowledge.

So...

My intepretation would be that this is perfectly legal: either the utility
was published about and then the acknowledgement is there.  Or it wasn't
and all is well since the potential researcher did not base *her* research
on SWI-Prolog.  Sic.

I say, let's keep it free: it is not a major nuisance (but a minor one, i
agree :)
