Which is exactly why you shouldn't look to YouTube for a good source of information.

Youtube isn't what it was 15 years ago. The content creators on there constantly try to reach a point where Youtube becomes their main source of income. They aren't interested in having it as a "hobby" otherwise they wouldn't get the views and you wouldn't hear about them. They put a load of effort into their videos and keeping it as only a hobby without making any money from it becomes too much of a chore.

And because the way Youtube is designed and monetised, these creators have to curate their content in a certain way to maximise views, which basically translates to making shit up so they stay relevant and get clicks. This is exactly why if you treat Youtube as anything more then an entertainment platform, with helpful guides here and there, you're hurting yourself.
