The opening paragraph includes this line:
--
Erdely said she was searching for a single, emblematic college rape case that would show “what it’s like to be on campus now … where not only is rape so prevalent but also that there’s this pervasive culture of sexual harassment/rape culture,” according to Erdely’s notes of the conversation.

If that's not promoting a specific cause, I'm not sure what is.
She was looking for a sensational story. Someone fed her one. Erdely still has a job. Jackie isn't in jail. All of the fraternities and sororities were punished. And the UVA president says "The story unfairly maligned UVa and many members of our community" and has yet to offer an apology for punishing the entire system without anything that resembled evidence, let alone an actual investigation.
I hope Erdely, Rolling Stone, "Jackie", and UVA are sued by the fraternity and entire greek system.
