I suspect the issue isn't YouTube per se but society. While they bear responsibility for their decisions any big entity which becomes the "mainstream" will receive the same pressure. With advertiser backing based on what they /think/ is good for their image regardless of what people other than the many noisy minorities (like every yellow journalist seeking a new moral panic) of all sorts think.

And rather than anyone involved learning they will push hard to be "more like TV" which we have been seeing for years on YouTube with every adpocalyose. If we cannot fix the underlying problem we are doomed to reoccurrence.
