Thats why it needed to be released months earlier, to allow it to filter through he corrupt MSM firewalls. The corrupt media and tech companies completely buried it, or just spun it as "election noise in the short time before the election.
The DOJ/Barr, overseers of the FBI, were probably expected to bring it to light. But they don't seem to have any desire whatsoever to bring politicians' malfeasance to light. So at the last minute it fell to Chinese dissidents, Bannon, and Guiliani to raise the issue.
