Both Atlassian's "open core" and RHEL are free software.
The difference is that Atlassian sells plenty of proprietary software and add ons too, while the only proprietary software that Red Hat sells comes from recent acquisitions (e.g., Ansible Tower), and it is all in the process of becoming open source.
Red Hat has a great track record for open sourcing software from companies that they acquired.
