Apple would no longer get $20 billion from Google for default search engine placement. Microsoft... and DDG or Yandex? might pay some, but nothing like that with the biggest bidder off the table. Safari funding would _definitely_ take a huge hit.
I don't think we know how much google pays for it right now. That 20B figure is from 2022. Also, that payment is mainly for iOS's Safari. Google would still pay Apple for search engine placement on iOS even if Apple stopped updating Safari today. What I'm poorly trying to say: I don't think safari development funding related to how much it brings in.
Also there is MS that wants to pay for search engine placement and it's fact.
