It wasn't an opinion piece, Wilf. It was a "style" piece, reporting on a trend.
It didn't say, "they shouldn't play this song." It said, "take a look at this: this extremely popular seasonal song has become a flashpoint in the #metoo controversy."
Where I think Rich goes wrong is that the article didn't just assume the immense popularity of the song; as small h points out, it reported it. So the fact that the song is still immensely popular doesn't require a correction to the article, as Rich seems to think, or somehow change the article's conclusion, or constitute news in itself.
Indeed, there wouldn't be any controversy about the song if it weren't very very popular.
