IMHO a nice & respectful letter is in place to make SWI-Prolog clarify their position. Just remember one thing: programmers in the academic computing community have a *hard* time getting credit for their software. So please let us (debian) be tolerant towards this kind of advertising claims where the only real problem is the discrimination of other academics! Let's propose that they use something like `Any published work that has used SWI-Prolog to obtain the published results should include a clear notice that this was the case. Notice that for distribution of derived works this is automatically the case since the Copyright notices must be retained.'
