It's difficult to imagine a real world scenario of what you've described.
"I insist on phoning someone who demands to record our conversation. We do not have mutual agreement on this matter, but I very much desire to speak to this other person. Therefore, I blame Apple for forcing me to hang up and not allowing us to speak."
The two parties haven't even agreed on the basic preconditions of a conversation. Unless someone has Stockholm syndrome, the disinterested party would never take a call from the other party in the first place.
This is equivalent to blaming GoPro for preventing an in-person meet from occurring, because one party insists on wearing one to the meeting.
Is it
really that hard to imagine?
Estranged Husband, calls soon to be ex-wife, to discuss child care arrangements: [Phone announces call is being recorded].
Estranged wife, who needs to get the child care arrangements ironed out pronto: “Do not under any circumstances record this call!“
Estranged Husband: “Nada” (or words to that effect)
Estrange Wife: “We need to have this call to discuss our kids but I’m not going to do it if your phone records the call”
and on and on.
You are all thinking of this like a phone solicitation system. Those types of operations are not using iPhones to contact people. These are interactions between normal humans, some of who do not want to be recorded, but still need to have the conversation.
