Just my two cents, but Assange had huge stakes in the election, namely the end of his legal issues with the US. Having Trump in office as opposed to Clinton give him a far better chance of having his charges dropped here. That alone would absolutely show a bias, especially given the fact that WL so aggressively went after Clinton and the DNC.
But then, there are these inconsistencies... If there wasn't an agenda, why would he only go after the DNC? At one point he had stated that he had no dirt on Trump or the DNC.

But just a couple of months before he was singing a different tune...

This guy has been holed up in the Ecuadorian embassy for years. A good portion of his freedom resides in the actions of the US. Going after Clinton to help Trump would no doubt be a great way to ensure he sees, at least for the US, that case dropped. Take every other issue out of the running concerning WL and Assange. If this were the only issue it should still be enough to make the actions and intentions, if not the facts they present, questionable.
