    I would also like to suggest that consideration should be given to
    allowing the notion of "attribution equivalency" to fall within the
    scope of GPL compatibility.

That requirement causes practical difficulties, because a person
making a change in a package--adding in a file that has this
requirement--may not know which other places such attributions must be
added to.  A person in learning enough about the code to make this
change would not have had to study everything in the package that
might contain statements giving credit to someone or other.
So he would not find it easy to follow this requirement.

Thus, although that license requirement qualifies as free software,
I think we should try to discourage it.
