I feel the same as most of you on here. Though sometimes a YouTuber can surprise you.
For example, I unsubscribed from Alex Day a number of years ago, because I no longer found his stuff entertaining - the reason why I watched him was because he was angsty and British and teenager-y and sarcastic, and I liked all of that. Then his stuff became stale in my eyes so I unsubbed. I came across one of his videos about 6 months ago, which talks about a viewers relationship with a YouTuber, about how they use them for a while and move on, grow as much as they can with a certain type of 'content' and then consume other opinions/people's ideology, etc.
It spoke to me quite a lot, and as such I subscribed to him one more. He had changed, as I had, but we were at different points in that growth. His candid documentation of that process gave me a realisation as a consumer of media, and his level of self-reflection that as a personality you will always have a shelf life unless you mature with your audience is admirable.
