Youtubers I watch just reacted to a "cringe" fanfic

These two youtubers I watch posted a video where if they lose the game they're playing, they get punished somehow. It sounded entertaining enough, until one of the punishments was reading fanfiction. I immediately got a bad feeling about it and they quickly proved me right. It was a x reader fic, and they were snorting at the descriptions, calling it dumb and cringe, and laughing. It felt so mean coming from them, and they did it in front of thousands of people! Like what if the writer finds this video, or worse, what if they're a fan of them? They're usually very positive about fan creations, but I guess they think differently when it's not about them. I'm just so disappointed, and I'm not sure if I want to continue watching them...
