This is a misconception. Many worlds has one fewer postulate then Copenhagen quantum, so there are operations you can do in Copenhagen that don’t make sense in Everettian quantum (measurement as a projection operator). Most of the physicist I know who object to many worlds object that it doesn’t have enough structure in the postulates to actually get predictions out.
Most interpretations are similar- they remove or introduce other postulates. Consistent histories, for instance, has a consistency operator that you wouldn’t use in another formulation.

The complaint is that MWI is not complete enough to give a satisfactory interpretation for the Born rule. Nevertheless, those who support MWI do believe that Born rule is essentially accurate.

Sure, its obvious empirically.
The question is- can you do without the measurement postulate and recover the Born rule. If you can’t, then Everett’s interpretation doesn’t work, you still have an ugly measurement postulate grafted on to the unitary theory, and you gain no elegance.
MWI doesn’t have different equations than “mainstream” quantum mechanics. It’s just an epistemological interpretation.
