I've been down the youtube rabbit hole. They are absolutely ruthless in their defense of their income. I've seen how little of a shit they give about content creators first hand. Their algorithm is very simple:
Will this affect us if we leave it up? If yes, remove. If no, leave there. The content doesn't matter, you could post a vid containing the cure to cancer and it's fine. Add in 3 seconds of some bullshit song nobody knows? Gone. They don't negotiate, they don't help, they don't offer any advice, nothing. They'll send you an email saying that you contravened their T&Cs and the vid is taken down and that's the end of it.
They went thru a phase where they'd remove the audio or stick ads over the content without giving a shit to claim some money but those days are gone.
This Fortnite player is generating income for Google and regardless of the community, it'll stay forever, because money > everything.
I've been on the dark side of most of these companies' products, whether it be Adsense, Adwords, Youtube, Google Analytics, the lot. I can say from first hand experience that when it comes to the bottom line, zero fucks are given. Ever.
