One thing I fear is RHEL starting to add in code that is not GPL'd, but starts to become necessary to properly run the system. Then if you have the full source, you will still be required to strip out their proprietary software and patch the GPL source to get it to work properly. They could also add specific files to the source that contains your "customer ID", based on needing to be logged in to download the source. I know that starts to get into aluminum hat territory, but stranger things have been done to maintain a business.
