There are a couple imprecise or omitted details about the OS in the text.
> Qubes OS is designed to be a single-user desktop operating system
At the moment, it's true, but multi-user support is planned: https://github.com/QubesOS/qubes-issues/issues/8958
> Note that the Qubes website and documentation tend to use the term "VM" and "qube" interchangeably
This is because in the future a "qube" will be able to run on independent hardware: https://www.qubes-os.org/news/2018/01/22/qubes-air. Then, VM and qube will not necessarily be the same thing.
> For example, installing software on a Fedora desktop is usually as simple as "dnf install package". But installing software to use within a Fedora-based qube requires several additional steps on Qubes OS, plus restarting VMs
If the software is from the main repo, you do the same "dnf install package" in a template. There are no other steps apart from restarting the App VM (which can also be avoided if necessary).
> Then again, it's also not encouraged—Bluetooth isn't considered secure, so why focus on making it easier to configure?
You can use Bluetooth securely on Qubes OS (but it does require some effort to set up): https://github.com/QubesOS/qubes-issues/issues/7750#issuecom...
