Apple of course does what benefits Apple, regardless of whether it benefits the user. 100% is 64 percentage points more than 36%. And due to the lock-in Apple could do away with significantly worse search than Google.

I agree that the heavy and intentional un-interoperability of Apple products is not a benefit for the users (although some hardcore claim it is). E.g. Apple clearly benefits from preventing sideloading (to force the App store rake) or alternative browser engines, but hard to see this having at least net benefit for the user.
