The criticisms were generally of a different sort: editorializing in their selection of leaks. "selective omission", if you will.
They have information about Trump but chose not to release it. According to Breitbart (so you know it's not from a "liberal media" source): http://www.breitbart.com/tech/2016/08/27/wikileaks-info-dona...

I don't know about you, but I feel like it would have been helpful for the people to know what they had on Trump. Seems oddly opaque and politically motivated.
It really doesn't help that they were selling explicitly anti-Clinton merchandise in their store: http://i.imgur.com/AjsWfqg.jpg
This is one example. In other cases, such as the Syria files, known-to-have-existed emails that involved Russia mysteriously weren't leaked and many people have speculated that stemmed from a pro-Russia bias.
If they were releasing everything they had, it would be hard to criticize. But when you see the pattern of leaks and omissions, it's hard not to make the argument that they are playing politics.
