Now I remember, the one marked non-free is already not distributed; 
instead, the binary explains how to get the real code. I dropped it since 
it advertises non-free software.

Of those without license according to debian, two actually are marked as 
public domain; I dropped all others.

Now it just remains to decide what to put into the license field.
