One reason could be the over - saturation of certain types of fanfiction. If there are a ton of fanfictions that follow the same tired tropes, like Harry always being the hero in the exact same way or his relationships being portrayed in a very clichéd manner, it could lead to this feeling of being fed up.
Maybe he's fed up because the fanfiction often misrepresents the Order's values or actions. In some fanfictions, the Order might be depicted in a way that doesn't align with how he knows them, which could be frustrating.
Well, there are several reasons. Dumbledore is this all - knowing figure in the original series, but in fanfiction, his actions can be seen as manipulative. He might be making decisions for Harry without really considering Harry's feelings or wishes. Also, Dumbledore's grand schemes might not always be in Harry's best interest. Harry might realize this and get fed up. For instance, if Dumbledore is using Harry as a pawn in a bigger battle against Voldemort, Harry would likely be angry when he figures it out. And Dumbledore's failure to prevent certain tragedies, like the death of Sirius, could also be a reason for Harry's disillusionment.
It could be a reaction to the quality or direction of fanfic. Maybe the idea is that the 'Harry Potter' entity, in this made - up situation, feels that the fanfic is not in line with the spirit of the original story. Fanfic can range from really good interpretations to ones that are completely off - base, and if the official side sees too much of the latter, they might want to distance themselves, which is represented by 'giving up' fanfic.
Authors might write it because they feel that the original series left some aspects unexplored. They are fed up with the gaps in the story and want to fill them in. For example, the daily lives of the side characters that we didn't get to see much of in the books.
It could mean that Harry Potter (the character in the story) is tired of or annoyed by fan - made fictional stories about him. Maybe he's fed up with how some fanfictions misinterpret his character or put him in situations he wouldn't want to be in.
Without more context, it's hard to say exactly who Harry is. But given the phrasing, it could be a reference to Harry Potter, as he is a very well - known character who is often the subject of fanfiction.
One reason could be the oversaturation of the fanfiction market. There are so many different fandoms and fanfictions that Harry Potter ones get lost.
One interesting 'Harry Potter Fed Up Fanfiction' could be where Harry gets fed up with the constant media attention in the wizarding world and decides to go into hiding in a Muggle village. He learns about Muggle life in a more in - depth way and discovers new forms of magic that are not part of the traditional wizarding curriculum.
He could simply stop reading it. If it's making him frustrated or fed up, the easiest solution is to just avoid it altogether.
One common theme could be exploring the darker side of the wizarding world that wasn't fully delved into in the original series. For example, the politics and corruption within the Ministry of Magic. Another might be alternative character developments, like what if Harry had turned to the dark side. Also, some 'fed up' fanfictions might focus on the mental and emotional toll the constant battles took on the characters, showing their weariness and disillusionment.
