You quoted the first sentence of the article. The headline is not supposed to contain all information from the article. We are not better off with a norm that we refuse to read past the headline and therefore consider the first paragraph of the actual article to be hidden.

I read the article, hence why I immediately noticed the disconnect. Mary Had a Little Lamb doesn't tell the whole story, but it doesn't say Mary's Magic Lamb Does Her Homework, either.

I guess intellectual dishonesty in links is so common some people don't even care anymore.
