Perhaps you are correct but we may never know.
I believe that the whole Russian interference and especially the "fake news" narrative is being pushed by establishment Democrats and the MSM for a number of reasons.
1. To deflect blame for their epic loss, crappy candidate and lousy campaign.
2. To discredit Trumps win. (Not to try to oust him, though) They want formal investigations so they can keep the narrative going as long as possible.
3. Censorship. And this I believe is the primary goal. You currently have virtually all MSM outlets and establishment Democrats (And a few Republicans) demanding that Facebook and Google "filter" trending topics that a specially appointed "task force" determines to be "fake news". Fake news most likely being anything the MSM doesn't want you to know about.
