“Word usage is what rules”
In that case we can delete your reference to ‘natural philosophy’, seeing as historical use isn’t relevant.
And your claim is a complete howler because people don’t use the words ‘science’ and ‘philosophy’ interchangeably.
Nobody describes Maxwell’s equations, for example, as an example of philosophy. Further examples are left as an (easy) exercise for the reader.
Meaning, history isn't relevant, either?
