I think that it is a bit frivolous to distribute software with
advertisment clause in main and not properly warning the redistributors,
who are the most likely persons to infringe the clause. We should
remeber that for other aspects of licencing and intellectual property
management, Debian is much more rigorous, so the presence of 4-clauses
BSD licences is contradicting the principle of least surprise, that is
usually a good guidance.
Importantly, the copyright holders of such programs are often not the
programmers themselves, but the universities, who nowardays face very
strong financial pressures and delegate more and more the management of
the intellecutal property to specialised services, who can be ran by
people who know nothing about the spirit of free software that blessed
the researchers when they wrote their programs.
This is why, as a personnal choice, I do not take the responsability of
introducing new packages with the BSD advertisement clause in Debian,
and I suggest others to refrain as well.
Anyway, I really think that there are good chances to obtain a
relicencing, that is by far the best way to find a solution that
