Perhaps he has his own vision of their story and the fanfictions he has read don't match up with it. He might be tired of seeing interpretations that don't resonate with his own understanding of Hermione, Ron and their trio's dynamic.
Maybe he's read too much of it and found the plots repetitive. Fanfictions often follow certain patterns, and after a while, it can get boring.
It could be that he doesn't like the way some fanfictions portray the relationships between Hermione, Ron and himself. Sometimes, fanfictions deviate too much from what he believes their relationships should be like in the original context.
Maybe because in those fanfictions, Hermione's bossy character is over - emphasized. Harry might feel like it doesn't stay true to their real friendship dynamic in the original series.
In some fanfictions, Harry might be angry with Ron and Hermione if he feels they are keeping secrets from him. For example, if they discover something important about Voldemort's plans but don't share it right away, Harry could get angry. He's used to relying on them and when that trust is broken, even if it's a misunderstanding, his anger can flare up.
If he still wants to be involved in the fan community, he can try to find some more niche or different types of fanfictions. For example, ones that focus on different aspects of the wizarding world rather than just Hermione - Ron - Harry relationships.
Some writers might create such fanfiction for the shock value. They want to break the established strong friendship in the original series to get readers' attention.
Perhaps Harry hates Ron and Hermione fanfiction because it can create false impressions. In the real world, their relationship is based on deep friendship, loyalty, and shared experiences. Fanfiction might deviate from this by adding out - of - character scenarios or relationships. Harry, who has been through so much with them, might not like seeing their story being told in a way that doesn't ring true to what he knows.
It might be because of a misunderstanding. In some fanfics, a false rumor could spread about Harry. Ron and Hermione, believing it to be true, might decide to distance themselves from him. Say, there's a rumor that Harry is involved with dark magic in some way, and they, being the 'good guys', think they need to stay away.
Well, it's simple. In the fanfiction world, Ron is sometimes portrayed as jealous because Harry is the famous 'Chosen One' and Hermione is super - intelligent. When they spend time together, Ron may think they are forming a clique without him. He's also a bit insecure, and seeing Harry and Hermione's camaraderie might make him fear that he's not as integral to their group as he wants to be. So, that jealousy pops up.
In fanfiction, Hermione might choose Harry over Ron because Harry often has a more heroic image. He is the Boy Who Lived, and his adventures are often more central to the main plot. Hermione could be attracted to his leadership qualities and the fact that he always seems to be at the heart of the action.
Well, they might be too caught up in the real events of their wizarding world. Fanfiction often takes creative liberties that could seem far - fetched to them. They've lived through the real Harry Potter adventures, so the made - up stories in fanfiction just don't seem believable.
In fanfiction, Ron might be portrayed as possessive of Hermione because in the original series, he has deep feelings for her. He may fear losing her to others, like Harry or new characters in the fan - created scenarios. His insecurities about their relationship could lead to possessive behavior.
