Copyright is a bundle of rights and copyright licenses don't have to license all of the rights in that bundle under the same terms.

You could make a license that makes copying and distribution not cost any money but charges for use. People who make distributions would then not have to pay anything for including the software in a distribution.

That seems like it would leave a lot of projects without any revenue, which doesn't seem fair in this hypothetical new world of charging for all your open source code. How many people are actually compiling and installing systemd themselves rather than having it come with their distro?
