Wouldn't this principle also make the OpenSSL license non-free?
If you distribute modifications to OpenSSL, you have to allow your
recipients to distribute your contributions in binary-only form.

I don't think there's any unfreedom involved here.  All viral
licenses impose some sort of restriction on how you can license
derived works (and in fact, some BSD folks argue that this makes
all of them unfree).  The GPL, the QPL, the NPL, the OpenSSL
license, and your sample license all have this property, and it
seems strange to me that you would declare the more _permissive_
ones unfree.  If the GPL had a loophole (let's call it "ASP" :-)
that made it possible to make GPLed programs proprietary, would
it then become unfree according to this principle?
