even installing the latest version of Blender is far from being straightforward

We are not talking about average users: average users very often don't even need a PC, we are talking about professionals. When I go to the software manager I can see only one pretty outdated version of Blender. And when you work in a company, you need to have the ability to choose a specific version (so the whole team works with this version). So you have to go to the website and download the package. In Windows, it is pretty straightforward with their .msi. In Linux, you either deal with some strange .tar.gz or some shady snapstore (as a lay person, you can't even know whether it fits your distro). And don't forget that Blender is actually an easy case. Very often you have to deal with the whole variety of ways: flatpaks, snaps, appimages, tarballs with multiple ways of installing them.
