I agree with you in terms of "original" content and what not but in regards to top 10 "informative" channel genre, we thrive off of already created content to an extent. Each video takes roughly around 4-5 hours of time to produce so I wouldn't categorize it as lazy, but if us not creating our own life hacks, our own sex scenes, or our own accidents, then you're right. Just how these channels work unfortunately.
But again, I'm on board with you. I know what you mean. I feel more fulfilled streaming rather than making these videos sometimes.
