Most of the fundamental packages in your Linux distribution are primarily written by Red Hat. Do you use Glibc, GCC, gnu utils, systemd, GNOME, podman, pipewire, Wayland, Xorg, or Flatpak for starters?
Red Hat is hardly a free rider in the open source world.
It is also worth noting that Red Hat created the Fedora Project. They created it so they could have RHEL (corporate) and Fedora (community) instead of just Red Hat Linux which they had before.
It always makes me laugh when people worry about Red Hat “taking Fedora corporate”. Fedora was created explicitly to be the community offering and is a key part of the Red Hat strategy. I guess not everybody knows their Linux history.
Many of the Fedora leaders and maintainers are Red Hat employees.
As for US influence, that has always been a thing. US law dominates the thinking. What you really need to worry about is the Linux Foundation.

I am going to go out on a limb and say that they like Debian but dislike systemd.
