On the one hand yes, on the other hand Assange kicked off the bad-faith by singling out the US under a guise of "just looking for the truth" while conveniently ignoring the failings of basically any other country.
This is not true. Wikileaks leaked material regardless of the materials country of origin.
He never "singled out" the US, they just got the most upset out of any of the countries who had material that leaked because it was a substantial amount of data that made them look bad.
But aside from that I also think the report isn't truthful for that matter, it is framed like Wikileaks turned it down.
