I guess. I think of fedora as more of a direct RHEL project. It's a "community" maintained project. But RHEL people are basically who run it. They sit on the board. They make the decisions. It's literally what was said above. A testing ground for RHEL. When you run fedora you are basically Red Hat's bug tester.
Yes and no. Red Hat employees use Fedora and work on it in their free time, sure, but I think the project leader is the only paid position.
If Fedora started doing something extremely weird Red Hat would likely step in since it's upstream for RHEL, but they've already diverged quite a bit (see: btrfs and -fno-omit-frame-pointers)
When Red Hat deprecated Red Hat Linux in favour of Fedora Core (now Fedora), it was explicitly meant for "the Linux hobbyist." In the same vein as Arch, you're not a proper bug tester, since you're not using any of the testing repositories OOTB, nor is anyone ever encouraged to do so. You just get the latest software that upstream (i.e. the Linux kernel proper, GNOME, KDE, Wayland, LibreOffice, Firefox, Mesa, any GNU tooling like coreutils, bash, etc) deems "stable" (i.e. suitable for immediate adoption in general use cases, not necessarily a production environment). Fedora releases are "engineered" to the extent that all this newfangled software can sit together and play nice in a general-purpose desktop use distribution that anyone from a hyper-autismo enthusiast to a paid Red Hat stooge can get comfortable with on some level. If you were a proper Red Hat bug tester, you'd be attempting to daily drive Fedora Rawhide over standard Workstation, KDE, etc. Also: important thing to keep in mind - you still have access to the latest and greatest stable software even if a new edition comes out. Do you think Fedora 42 users are stuck with marginally older kernels and marginally older GNOME/KDE releases? I would hope you don't, considering how rapid the turnover in software is on an X+2 release cycle.
Between Fedora and Artix, I gleefully prefer Artix with XLibre and Cinnamon over Fedora Workstation with Wayland and GNOME Shell. Even so, it really must be said that Fedora's not particularly unpleasant to use even with full GNOME Shell and Wayland. I thoroughly detest the GNOME team, they probably want me to die because I'm a literal minority who aligns with the evil heckin awful Nazirino chuds (race traitor looool), Wayland is
almost "good enough," still not "adequate," let alone "excellent" and won't ever be due to design philosophy outsourcing things to compositors with no fixed specification, yet it remains woefully inadequate insofar as remote desktops/VNCs which I
do like to use whenever I'm interacting with my Raspberry Pi. As it stands right now though? Fedora Workstation as an "engineered" release meant to make all this crap play together somewhat nicely gets the job done. Mind you, the correct answer's still Artix-OpenRC with XLibre any day of the week, but as a "lazy man's bleeding edge Linux distro," Fedora's pretty damn ace if you're willing to bite your tongue on your biases. Plus, it's kinda nice not having to manage AUR packages or the AUR "helpers" that get in the way more often than not (COUGH COUGH YAY COUGH COUGH) when the official repositories and RPM Fusion already have all my needs comfortably met, along with a good 85-90% of my wants. Anything that isn't available is either a Flatpak, an AppImage, or a COPR repo away (i.e. ungoogled-chromium).
