That said, nothing wrong with pointing out that it's an unfair attack now as it may have been in 2011. (I didn't know Ball has written about Assange extensively until googling it after reading the BuzzFeed piece).
Since it's a piece by someone who has a personal dispute with Assange, it has to be taken with a grain of salt. I think its most interesting contribution at this time is its argument that Assange, for better or worse, hasn't changed, it's the world.
