What people call OOP is OOP, literally by definition. Alan Kay may have coined the term, but his version of OOP has nothing to do with what is commonly understood today, and is therefore irrelevant.
That's silly and not how definitions work.
definition noun def· i· ni· tion | \ ˌde-fə-ˈni-shən
an explanation of the meaning of a word, phrase, etc. : a statement that defines a word, phrase, etc.
In other words: words or phrases have actual meanings, regardless of what people call them.
To give you an example, people use "their" instead of "they're" all the time. It doesn't mean that "their" means "they're".
