I've Got It
So Logan recently posted a video featuring a suicide victim literally hanging from a tree. The video thumbnail featured Logan looking wide eyed with the suicide victim hanging in the background. The TLDR version, much furor ensued. At some point YouTube featured the video in their trending feed which strangely, didn't help matters at all.
World wide press coverage followed, universal condemnation of Paul and YouTube. Pauls fan base, predominantly children attempted to defend him, which only made the situation worse. Advertisers examined their ad budgets and no doubt many went with " Facebook looks good this year".
YouTube ad revenue one would assume took a turn for the worse and YouTube took to small Creators as a convenient scapegoat. Logan got a slap on the wrist, most Creators got demonetised (or at least will in February) and the YouTube powers that be, collectively high fived advertisers and made arrangements to catch up at Burning Man this year.
There you go, in a nutshell
And then Facebook was like "no more ads on facebook" and the advertisers give up on social media then spent money on good old tv ads.
