I don’t think the current Red Hat controversy will have much impact on Fedora. There are the three reasons why I think so:
While Fedora is not a fully independent distribution, the Fedora Council has both members from Red Hat and members from the community. It may be wishful thinking, but I believe that, if Red Hat tried something iffy with Fedora, the community (including people in leading positions) would protest.
Fedora is upstream from RHEL, so it doesn’t directly profit from RHEL source codes being fully open. Instead, it’s the other way around; Fedora’s sources are the basis of CentOS and then RHEL, so any bugs fixed in Fedora benefit RHEL.
Fedora is also Red Hat’s tool for influencing the Linux ecosystem at large. When they want other people start using some technology (Flatpak, PulseAudio etc.), Fedora is a good way of disseminating it.
P.S. There might be some inaccuracies. I am just a user; I am neither a developer nor in any leadership role.
