I'd wager that such authors find it more fun to play around with how they'd approach a given work in their own lens, and to that end, how to "improve" it or even just riff on it; the self-insert dimension-hopping is just the avenue they choose to explore that sort of thing in.
Yes and most of fanfiction in this genre that I known is often add Harem and RPG Game System for MC to make him stronger than canon MC or various universe he is hopping which in Dek-D & Readawrite in Thailand is saturates with these low grade fanfiction and we don't have Mary Sue Hunter type of Character as Rival of MC due MC can do everyting they wanr without any consequence such as killed charactwr that author hate and get their own waifu then hopping into nww universe as do same
Trying to find a good fanfic to read, only to see "My Overpowered Self-Insert Has a Million Girlfriends from All My Favorite Shows #3453953" does sound like it can get annoying if you have no interest in that sort of thing. I don't think they're as common in the West, but I also don't read that much crossover fiction and avoid explicit self-insert stuff a lot as well.

I think it's because most successful canon has industry standard story conflict. Self-Insert Fix-It Fic writers are exercising their problem-solving brain parts, so if the problem is that...like...Elizabeth believes everything bad she hears about somebody that she already doesn't like, and Darcy is socially awkward, then the most obvious solution is for them to not be like that. The second most obvious solution is that the plot humbles the characters enough for them to learn and grow and develop as people...
That said, defending the way the story is against an antagonist that wants to change the story sounds really very interesting. But I think that requires an appreciation for the conflicts and resolutions as they are, to begin with.

Let me ask you a question Why would a Dimension-traveling crossover fanfiction prefer having their Self Insert characters change the story of fiction rather than defending it from an enemy who wants to change it?
Well, I wonder why a protagonist of this type of fanfiction wants to alter the reality of that fiction ignoring its effects rather than protecting the reality of that world from the people who will do the same for the protagonist
