Not so. If you look at social blade it reveals the true numbers. Blizz either has friends in Google/Youtube or is working directly with them to get rid of the bad numbers. You'll notice that the upvotes never go down, so It can't be a re-upload. The only number that declines is the downvotes.11/03/2018 05:17 PMPosted by WuhjikôDifferent uploads.
Archive pages reveal this to be true, or confirms it. Socialblade cannot be wrong in this because the Archival Caches show it has the same URL from before till now, going through that shows that the number of comments and down votes repeatedly fluctuates. The upvotes continually rise, never decline.
There is no way this isn't deliberate manipulation and damage control.
