Do i pay for iphone users?

I heard that Apple is not paying for the ChatGPT installations on the iphone.
Is that really correct?
If so:
Am I paying for iphone users in the end?

I am asking, because the last thing I want to do is giving money to apple (direct or indirect) and I definitely dont want to pay for free-riding iphone users.

Could anyone shed some light on that situation for me?
Thanks so much.
