Fedora is community owned, it’s just the upstream for RedHat. RHEL is based on Fedora. So I don’t really think there’s a cause for concern, unless RedHat uses its powers within the Fedora project (some people involved with the Fedora project are RedHat employees) to make things worse for Fedora but if they do, Fedora will lose users, so RHEL will lose free testers.
