Could you be more elaborate?

The reason I asked is that I find the OSD fairly vague in this regard.

The above suggestion does not preclude, say, military personnel from
using the software, unless they are using it for lethal purposes.

Likewise, copyleft does not preclude commercial users from using the
software, unless they modify (and redistribute) the software without
making the modifications available.

So the question boils down to this: does the OSD prohibit discrimination
against courses of action?
