Ah, now I see.  Below is the wording from the web page I mentioned 
previously (http://www.bioinfo.rpi.edu/~zukerm/rna/mfold-3.1.html):

Versions 3.xxx of mfold for Unix and Linux operating systems are available 
via a free license for academic and nonprofit use only; commercial use is 
available for a fee. Copyright © is held by Washington University. 
Washington University seeks additional licensees for commercial development 
and marketing and invites all interested parties to submit proposals. 
Please direct all requests for licensing, information, and limited 
evaluation copies to Washington University's Office of Technology 
Management by E-mail ...

I suppose the license is there to allow academics and non-profits to use 
the software, but the copyright is present to prevent dissemination and 
have commercial users pay a fee, especially if the code is included in 
proprietary software.

Oh well, a bit off-topic now.  Anyone else want to chip in on the original
