I have not discussed logos with a lawyer, but I doubt that the rules
are so simple.  I've seen advertisements where the advertiser shows a
competitor's product; I saw one last night, and the logo seemed to be
visible.  I cannot be absolutely what the situation was, but I don't
see why the competitor would have given permission for this, if it was
really up to them.

I asked our law professor about the issue, and I will report
what he says.
