This concept is called legal personhood:

When it's not a natural person (ie, a human being) it's called a juridical person:

"Person" is in this usage a piece of legal jargon.
That's all well and good, but we're not talking about the rest of the article. Only the bit that says "It’s widely known that Corporations are People" — which is not about legal personhood. "People" always refers to those found in the flesh. Which, like before, is why the law is careful to use "legal persons" instead of "legal people" when the plural form is relevant; to not confuse non-human legal entities as being people.

There is no usage of "Person" here. It says "People". The plural of "legal person" is "legal persons", so clearly nobody is talking about that.
