A prime example was a video with millions of views on a very popular channel about 9/11 conspiracies. Did the YouTuber believe them? No. But cranking out a 10m+ video every day is more important than what he believes.
Then you look at high quality channels who put out a video once a week, or even month, and they are forced to rely on Patreon (which is a great platform!).
Not sure what the solution to this would be, but I feel similarly on the wading through garbage to get to the good stuff.
