Forbidding Google from requiring exclusivity is not the same thing as mandating that Apple accept payments from others. Google can afford to pay more per user/click because of scale economies; their cost per user/click is lower. So, great, Google will pay Apple $20/user/year on a nonexclusive basis, and Firefox or whoever are free to match or exceed that, so long as they don't mind losing money on every user.
