The docs page is broken with a dead link I think?
The magazine page is pretty old, I guess it also needs a link update needs a new page, if this is how it is done
The Spins and Labs websites dont contain the section with Fedora Mediawriter, unlike the Workstation page.
The Atomic Desktops pages are fine.
No, the magazine article is out of date, so someone needs to write a new one on the subject. The magazine articles are not to be considered long term reference material, and there will be no updating of old out of date articles. They are ephemeral, much like containers, and will go out of date repeatedly. The Fedora Magazine should not be considered as a source of (current) documentation (unless the article posted is current), and users should be encouraged to read the (official) most recent documentation on the subject matter in question to have the latest up to date info.
