Not the same question...
You are talking about the amendment. The article is talking about the court decision.
These are two distinct things, in my view.
So, just in case you missed it:
In 1884 the Supreme Court held that children born to Indian parents were not born "subject to" U.S. jurisdiction because, among other reasons, the person so born could not change his status by his "own will without the action or assent of the United States." And "no one can become a citizen of a nation without its consent."
