No, it might very well be fair use. Has the copyright owner
complained? If the owner doesn't complain, then why should you?
So? Is the copyright owner objecting and not telling anyone
about it? If so, how would you know?
I know because the author placed a copyright notice with the work. That
made it clear that the author did not want it copied illegally.

If the OP copied it in accordance with fair use laws, then there
was nothing illegal about it.

You said:
"It's never considered fair use under copyright law to quote a
substantial
newspaper article in its entirety without the author's permission."
That just isn't correct. It is often considered fair use to copy
an entire newspaper article.
Because you said so?

No, because it is the law. Go look it up yourself.

What would be the point of even having a copyright law if people
could just publish your entire work without your permission and you could
do
nothing about it?

The entire work is the newspaper. If someone copied the entire newspaper
without permission, then the newspaper could do something about it.
The OP only copied one article.
