I don't really see a problem with it. It's a "you do not have the
freedom to make this program less free" restriction, similar to the
restrictions imposed by the GPL.

Essentially, it's a question of how to resolve competing freedoms, and
the meschach licence took a different view to the GPL. It's just a
different (and incompatible) sort of "free".
