There could be several reasons. Sometimes, fanfiction authors like to experiment with different character dynamics. By making Bill Weasley not so appealing, they can explore how other characters interact with him differently. Also, it could be a reaction to the over - idealization of some characters in the Harry Potter fandom. If Bill is always seen as a hero - like figure, some authors might want to break that perception and show a more flawed side of him in their fan - made stories.
The writer might have personal reasons. Maybe they didn't like how Bill was presented in the books, so they use fanfiction as a platform to rewrite his character in a more negative light. It could also be part of a plot device. For instance, if the fanfiction is about a character who has a grudge against Bill, writing him as not so great can help develop that storyline.
One possible reason is to show a contrast. Since Bill is often seen as a reliable and good - natured character in the original series, making him 'suck' in fanfiction can create a shock value and make the story more interesting. It can also be a way to explore the flaws of a seemingly perfect character.
Well, in some fanfiction, a writer might portray Bill Weasley as 'sucking' perhaps because they want to create a different or more complex character arc for him. Maybe they have a different view of his actions or relationships within the story. It could also be just a creative choice to add drama or conflict.
One reason could be that the creators of such fanfiction are die - hard Snape fans. They might feel that Snape is the most interesting and underappreciated character in the 'Harry Potter' series. So, they create fanfiction where Harry Potter, who they may see as getting too much attention in the original, is not as great, to put more focus on Snape.
Perhaps Bill is preparing Harry for a secret mission. He might be training Harry in stealth, disguise, and communication spells. This could involve Bill using his experience from his travels around the wizarding world to give Harry unique insights. Bill could also introduce Harry to some of his contacts who could provide valuable information or assistance for the mission.
She might hate it because it could change the way people see her character. In the original story, she is a strong and independent person, but fanfiction might portray her in a wrong way.
Well, Hermione has a unique charm. In fanfiction, Bill could be attracted to her because of her strong sense of justice. She is always fighting for what's right, and Bill, who has seen a lot in the wizarding world, might admire that. Also, her loyalty to her friends is something that could draw Bill to her. He might see in her a kindred spirit in terms of being there for those he cares about.

One great Bill Weasley and Harry Potter fanfiction is 'The Unseen Bond'. It delves into the relationship between Bill and Harry outside of the main events in the books.

One possible reason could be that in the fanfiction, Bill might be depicted as more mature and worldly compared to Ron. Hermione may be attracted to his experience and the different perspective he can offer.
He might be developed as a protective figure. Given his family's connection to Harry, he could be extremely determined to keep Harry safe. This could lead to him being overprotective at times, causing some tension between him and Harry as Harry wants to prove himself. His protective side could also show his loyalty to his family and friends, which is a key trait of the Weasley family.
His character might become more nurturing. Bill is already a brave and capable wizard, but raising Harry would add a new layer of responsibility to him. He'd have to be more patient and understanding, as Harry has his own traumas from his past. He might also become more protective, like a father figure.
