I’ve gotten the impression that for some creators, part of the reason is how easy it is to be demonetised on YouTube. The monetisation filter has become sensitive and puritanical that people even self-censor confronting words now, like “murder”, or “rape”, or “suicide”… I don’t know what TV news or current events shows are like today, but from what I remember watching when I was younger, I doubt any of that would be monetisable on YouTube today.
