Yes each of those websites still use PHP under the hood. But by that argument each of those websites can be counted as using C as well. As well as machine code.
It has nothing to do with the code being spaghetti or not. It's about a level of abstraction where I no longer consider something made with wordpress as something created with PHP. The PHP was allready created and then someone just clicked a few menus to choose what existing PHP he or she wanted.
The more fitting category would be just calling such websites "Wordpress" websites and not PHP websites.
The categorisation you are trying to make us accept is ridiculous.
I can deploy a python web application I have written to a new web server within minutes by clicking deploy in bitbucket.
So using your definition:
* The code is already written.
* I clicked a few menus and I had the python code I wanted running.
It isn't a python application. However the web application when it receives a request will run python code. It is clearly a python based web application.
I wouldn't consider it python code if it is a cookie cutter website where the creator didn't have to write a single line of python. It's not about deployment it's about the process of creation. Why don't you consider each and every website running PHP also a C website?
