This is not quite accurate. Large institutions with very slow processes and onerous governance will be very much tied to RHEL 6 for some years. It indeed is a very important part of Redhat's business model. Enterprises will purchase extended support for RHEL 6 going up to 2024

That extended support isn't as comprehensive as the standard support, though. With each stage the amount of components and the degree and types of patching etc reduces.
