Any license that mandates a requirement to send all modifications to the

In fact in one of the license this is a should and not a must, Karl
Berry (texlive maintainer) thinks it is right and I agree with him:
"All modified versions should be reported back to the author."
And the clause in the other license has been removed by the author of dvips
recently.
