Google is preinstalled on billions of phones for free, and this will not be changing anytime soon.
How are you going to get millions of old folk that dont care about Bing vs Google to change the default search engine on their smartphone if you are Bing?

Their own search engine isn't that far off Bing and both are way behind Google.
On the other hand, it's the perfect opportunity to put the 16 ML cores in my phone to work. Local Siri uses a generic model today, but I would use an Apple search engine if it could deliver genuinely personalized results instead of the SEO wasteland Google offers.
It's what powers the Suggestions feature.
