I feel like there's a huge difference between 'people who produce YouTube content' and 'influencers'. As others have said, the former are just like any entertainment and/or informative role. The latter, as is my understanding, seem to be more about promoting themselves and getting as much as they can out of sponsors and their audience.
Both can work hard, but the goal is different.
I watch a lot of YouTube channels, and (IMHO, of course) it's no different from watching TV or listening to the radio. You've got decent people who want to put something creative and/or informative out into the world, and you've got self-involved dickheads who are in it for themselves.
