In other words: this is all speculation, there's no evidence of coordination other than it looking like it for people who are already wanting that as their narrative.
We don't know Wikileak's source. Assange has said it wasn't a state actor or Russia and he has a flawless track record for the information he provides. There's not even a real level of reliability in knowing who hacked the DNC or Hillary servers. The servers were never given to law enforcement to look at, and there are details in the story that don't add up to it being an external party that took the data.
It's amazing that people cannot see beyond their own self-righteous indignation enough to discern that this is what's happening.
