I did proceed my statement with "As far as I know", meaning I'm willing to be educated differently.

Again, I'm willing to be told differently, but the big advertisers that I was aware of were Disney, Coke and Car Manufacturers, none of which ever seemed to return, despite Youtube bending the knee in trying to get them to return.
As another comment says, Youtube loses money delivering content without adverts. As the number of demonetized videos increases, so do the losses from those videos.
My point is essentially that they although they made these changes, it doesn't appear to have benefited them. The number of "controversies" increases regardless of what they do, but now all that happens is that they hurt the communities they want to protect (such as LGBT) and annoy others.
