Open source shareware?

[Forrest J. Cavalier III]

Can someone point out the OSD violation of a shareware 
license such as the following?  I realize it violates
the spirit of the OSD, but I cannot find where it violates
the "letter" of the OSD.  The OSD is silent on "use" and
I think this illustrates the problem.

Russ Nelson has indicated that the specific wording of the OSD
is important.  Can we find a way that the OSD rejects this kind
of license?
