There is nothing to stop you selling a distro or selling commercial software to run on top of linux. A number of companies do.

they sell RHEL - you can't download it for free.
Edit: not unless you count CentOS, which is RHEL with all the redhat stuff stripped out and doesn't have the infrastructure around it that RHEL does
