We knew this. It has been confirmed many many times and years back.
There was not even an outline for one movie, The Force Awakens. They made it from the bottom up. They said we need this character, this character and this character. Now lets try to connect and make a story around them.
There was a feature called "Balance of the Force". This was the most interesting bonus to me. It was explaining the story and what has happened and why things have happened. Never before they needed or tried to explain what has happened in a movie and release it day and date with the first home...
I think their news should not be spread. It's like feeding trolls. They should be ignored completely. The more you talk about them, the more they become legitimate. It's exactly what they want.
It comes from the top. Why should we expect people to be decent, loving and kind? Where they should learn it from? (All rhetorical questions of course :))
Also about Hayden Christensen. I don't think we can blame fans for him not getting roles. Maybe, just maybe he is not getting big roles...
