I would imagine that being written in PHP is the main selling point for end users who don't have the knowledge to set up a Node.js based website.

Also taking in the global context, most hosting plans that are payed in the specific country currency run on PHP without any configuration, just put your PHP files there and puff...magic, a website is running

Yes it is. You don't have to setup PHP. It comes preinstalled and preconfigured on most hosting products. You can copy Ospari and start to blog. No step and no configuration needed.
