FWIW, GOS is an excellent project, but I don't think it's a good fit for non-technical users. But there's nothing stopping someone from creating a distribution of it with a preconfigured Google Play sandbox, some sane defaults and applications, to provide technical support, and to streamline the installation process, or even sell devices with it preinstalled. As long as that entity is trustworthy, it would be a good alternative for people who want to leave the Google/Samsung/etc. ecosystem, but don't have the technical knowledge or want to bother with installing and configuring GOS themselves.
If the web install guide only had to cover installing from macOS, ChromeOS and Android, it would be significantly simpler. Most of the complexity in the install guide is to work around issues with desktop Linux distributions.
