depends if they can monetize that spot. So either ads or subscription. It is as yet unclear whether ads/subscription can generate sufficient revenue to cover costs and return a profit. Perhaps 'enough ads' will be too much for users to bear, perhaps 'enough subscription' will be too much for users to afford.

right now google pays apple almost $30b a year to be default search in safari. google only has one icon on the home screen (YouTube). just originating google searches could be worth tens of billions. so i don't know. there are a bajillion ways to monetize.
