This is exactly why HACKING lost the election for Hillary:

Whenever a crooked politician is caught in a lie, their standard strategy is attacking the source. I say that I really don't care what the source is or the source's motives, all I care about is whether the information revealed is accurate and factual. You'll notice that Hillary's minions don't even bother denying the DNC's dirty tricks, they just try to shift the focus away from the DNC and towards the hacker. The point is, if the DNC and Hillary weren't running such a sleazy campaign, then they wouldn't have to worry about hacks or leaks.
Here's an analogy: your worst enemy videotapes you committing a crime. He submits this information to the police. Even though his motive was harming you rather than a sense of justice, it doesn't change the fact that he has evidence of you committing a crime.
