Another point of contention on that is that the Hyuga are Purists that adhere to their clan matters ONLY within the clan and want all marriages to be exclusively within the clan too I am assuming so why would they even appprve of a marriage from the main branch's first daughter with an outsider, no matter how prestigous he ended up becoming or how distantly related they are? But they BS'd Hiashi to being a doting, embarassing grandfather, but besides the point It is true that the In-la dynamic between Naruto and the Hyugas is very strange and OOC at the very least
And the case could be made that the Hyuuga wanted to lowkey oust the Uchiha all along, making them the most powerful clan in the village. (That's their only family backstory right? Sacrifice everything for the benefit of the clan. *looking at you neji*) The Uchiha massacre, while a tragedy, worked in their favor.
So when their only un-sealed shinobi, Hinata, manages to catch the eye of the village screw-up-turned-powerhouse, you can imagine that the wheels would already be turning within the clan to make sure there is no way Naruto slips away.
Fast forward, then, to the next gen, they're married with kids, and the world of Konoha has the Hyuugas cemented as the most powerful clan in the village with a direct line to the Hokage. What would they do to keep that power? What wouldn't they do?
How is Naruto not defacto head of the next Uchiha-type clan? Not only did he not break the cycle, he seriously is just restarting the Uchiha clan dynamic within the village for the next generation!
