Differences in interpretations will happen but the YC rule that founder drama is too often a problem continues to exist and it shouldn’t be a surprise.
I'm not sure what rule the OP is referencing but otherwise reasonably successful start-ups often fail because founders clash on key parts of their vision (or behave in toxic ways towards each other or to other people in the company). This can very handily wreck your company or at a minimum substantially damage it.
