I wish they didn't use that ambiguous word, though. The evidence seems pretty clear, most most people won't read past the headline and will think there's still doubt.

"It sure looks like there was an egg cartel after all" would give the same rhetorical effect but be much clearer.

Sadly, changing headlines won't solve functional illiteracy, in this case, the belief that the headline is the story.
