As I said, "That may be true in some jurisdictions, but it's not axiomatically or definitionally true.". The law is emphatically not an axiom, nor is it definitionally right or wrong, or correct or incorrect; it only defines what's legal or illegal.
When the article raised the question of whether "building software is an engineering discipline", it was very obviously not asking a question about whether the term 'engineering' is legally restricted in any particular jurisdiction.
There is no such rigorous definition for "software engineer" which normally is just a self-granted title meaning "I write code."
