The tournement sponsors can change their rules. For example, they can
require all entries to be free software.

How will he find out?

Is he making money selling and/or competing his program or has he
registered his copyright? If not is he prepared to spend tens of thousands
of dollars and years of time to get a judgement that tells the infringer
"Don't do that"?

It is the Debian Free Software *Guidelines*. That paragraph was put there
for Tex and Perl. I think I have a pretty good idea of its intent.

Please re-read para. 4, especially the two sentences in parenthesis at the
end. Debian only grudgingly permits clauses that require that the name be
changed. I don't think that one that specifies exactly what it must be
changed to would be accepted.

There is no line of demarcation. If I include any of your work in mine I
have infringed your copyright (fair use does not apply here).

But the kid slaving away in his basement over his chess program has no idea
what Prof. Hyatt might be happy with or if he is reasonable. He knows only
what the license says.

It does. The clone author owns the copyright on those lines. Dr. Hyatt
owns the copyright on the rest. The result is a mixture of two works: a
derivative. Copyright makes no judgements as to what is or isn't
consequential. Otherwise everything Hollywood has produced in the last 50
years would be in the public domain.
