I don't think it's a technology issue, it's a business one. They have built a position on customer privacy and moving into the search/ad business is inconsistent with that. Take Google's money and let the Goog take the flak on privacy.
Those are very different worlds, that require organizations built in very different way.

Not for Apple - they have hardware excellence in their DNA, but the web and internet services aren't a core competency (yet?). They have made huge strides from the disaster that was MobileMe, but they are nowhere close to where the Bing or Google search teams are.
Yes, thats why my $4000 macbook pro keyboard inserts double keys strokes on 50% of key presses. The excellence must all be in the magic touchbar that periodically stops working so I cant even use vim because the ESC key is on a broken touch screen.
I mean, sure they could, but what would that expense gain them in terms customer experience?
Furthermore, as inquiries of monopoly power poke at Apple, there is likely little appetite (if there ever was) to expand their monopoly horizontally into other industries.

This being the top concern doesn't really mesh with the game theory of google giving them $15B. If everyone believed UX was apple's primary concern, and that google was the best option, then google would not have to pay.
Google is paying for Apple to not have the default be Google search. If Google wasn't paying, Apple would be able to offer the default search provider to someone else or make it a user selectable choice in the new phone setup.
Google is paying to keep Apple from thinking about their own provider or shifting the default to Bing.

Organic search from a mobile device is 60% of all Google searches. If we take the 50/50 breakdown for iOS vs Android and apply it there, 1/3rd of all google searches are from iOS.
That's what Google is paying for - making sure that people who don't care about their search provider continue to make up 1/3 of all of their searches (and data gathering).
The next thing to consider back on that "what would the expense gain" ... does Apple have the resources to spin up a 1/3 google data center. I mean, yea they do... but that's expensive and if they aren't selling adds, it is purely an expense.
