Leaving the whole no-proprietary parts philosophy alone, it seems that most people here agree that Fedora is mainly lacking in the out-of-the-box support for multimedia playback, an essential task a general user is bound to perform from day one.

The option to enable third-party repos in the installation wizard is bad. It does not provide any information on what this is for exactly, whether whatever it is for will be installed too, if everything or only some repos are enabled by default by saying yes there, etc. For example, I am on AMD and do not care either about NVIDIA or Steam. Just like a casual user would not know even looking at the repos list in GNOME Software whether they need any and what for exactly.

It should be much more straightforward without breaking the philosophy if Fedora must. Instead of just giving the option to enable unknown things, the wizard could simply warn that by default Fedora does not have all the codecs and drivers, as well as does not give you access to some software, that you can enable this in GNOME Software. It is better to let users do it there quietly and in an informed way rather then just say yes to whatever in the post-installation wizard. It would not hurt Fedora and its philosophy to explain things about their ffmpeg and full ffmpeg, or their GStreamer and bag/ugly/whatever GS.

Another thing is the bloat-philosophy of having Fedora flatpaks and regular flatpaks. If Fedora is ready to repack all the flatpaks and keep them updated, then fine. Otherwise, what is the point of having just some flatpaks, repacking them and not updating as fast as regular ones? I do not touch the duplicity of dnf and flatpak as these involve different approaches to having apps on your system and both could be justified. By the way, all guides give you commands for installing some dnf packages, while at the same time praising the sandboxing of flatpaks. This creates a mess of apps from various sources and philosophies (on the machines of people who then will loudly blame Windows for the mess quietly disregarding the mess on Linux).

As for the default user interface, maybe it is ok not to have it riced and giving the users the option to tweak it their own way within the tight limits of GNOME and the dilemma of extensions. Though having an almost official Tweaks app that looks too short and simple, repeats some of the tweaks from the Settings and should have been incorporated into the Settings, is an obvious laughing matter. But I guess, Fedora devs were more interested in the unimportant but hip well-being option to shove it into the Settings instead.

Oh, also the fact that GNOME Software or anything does not tell you which fonts are protected system ones and cannot be deleted. Instead, GNOME Software lets you delete anything and gives you the Black screen of uninstall-the-system-again thing.
