I don't discount that it's possible that NYT headline policy could have changed in the last decade, but sensationalism when it comes to newspaper headlines is the historical norm. "Clickbait" is an ancient phenomenon:

"In A History of News, Mitchell Stephens notes sensationalism can be found in the Ancient Roman gazette Acta Diurna, where official notices and announcements were presented daily on public message boards, the perceived content of which spread with enthusiasm in illiterate societies."
