Term "functional" has been watered down and has different meanings now. However, the original meaning comes from mathematics and is still in use. You might not like it, but that's how it is - hence why I deliberately disambiguated it in my response to make it clear.

This has also nothing to do with gatekeeping.

If you disagree with me, maybe you should go to Wikipedia first and change it there, because by what you say, Wikipedia does it wrong too.

And functions links to:

> The subroutine may return a computed value to its caller (its return value), or provide various result values or output parameters. Indeed, a common use of subroutines is to implement mathematical functions, in which the purpose of the subroutine is purely to compute one or more results whose values are entirely determined by the arguments passed to the subroutine. (Examples might include computing the logarithm of a number or the determinant of a matrix.) This type is called a function.

> In programming languages such as C, C++, and C#, subroutines may also simply be called functions (not to be confused with mathematical functions or functional programming, which are different concepts).
