Lots of people new to Linux get recommended Debian-derived distros, and so end up with distro packages that are a long way from bleeding edge. If they’ve just come from Windows, they’d have been using the latest release of everything they use, as most software projects don’t even announce a release until their Windows binaries are ready, and many auto-update. That means that a lot of people have being presented with versions of things they stopped using two to four years ago as their first Linux experience, and obviously they don’t see that as good enough. Most people don’t want to run versions of things that old, especially now there’s so much stuff to package that downstream packagers can’t feasibly backport every bug fix to older versions of every piece of software, so running an old version gets you old bugs rather than a balance of avoiding new bugs at the expense of new features.
Sometimes things look simple but have complex knock-on effects, and it takes an expert to notice that there’s anything that might be a problem. At least none times or of ten, there’s no problem and it looks like someone’s wasting their time, but it occasionally saves a much bigger headache later.
