I will say that Oracle does contribute to gcc, gdb, and other parts of the GNU tool chain. I interviewed a few years ago with the team that does it. I don’t know how large the contributions are, but they seem super passionate about what they do and believe strongly in giving back

They might have an occasional commit or two but clearly they can't stand behind their own promise of developing/supporting an EL distro the way Red hat does. I also don't see it changing tbh. I don't see troves of Open source engineers at Red Hat(or other companies) making a bee line for joining Oracle.
