Exactly! This "confirmation" is purely based on random people on the internet saying it is so. There is no twitter, blog, interview or anything where it is stated which Infinity Stone the Aether is.

I remember one interview with Kevin Feige. He confirms that the Tesseract is the Space Stone and that the Aether is an Infinity Stone, but not which one. (but we knew that from the movie) James Gunn has confirmed on his twitter that the Orb contains the Power Stone, and the Mind Stone is now confirmed in Age of Ultron. That's it; nothing else has been confirmed.
