Redhat is a commercial linux because they are competing with other os/distro in this market. If I pay Joe $5 a month to keep my ubuntu up to date it doesn't make ubuntu a commercial linux even though I am paying for a linux service. These companies building supercomputers are competing in producing supercomputers. Not in providing a linux disto and providing a service for said linux. I very much doubt I could get access to their linux disto and linux service without first purchasing a supercomputer from them.
