the burden has always been with the customer. But the fact that apple had been able to mandate the use of their IAP means the customer could not have exercised this "burden" until now!
Customer rights are always balanced with corporate rights, and laws and rules are there to assure neither customers nor corporations act in detrimental ways to society.
Customers can choose what they want to succeed, but none of the choices should have strong moral implications. I shouldn’t have to choose between destroying the env. or not, or support crushing rival businesses or workers rights or not, etc.
So no, I don’t think it’s customers burden to have companies behave. Except if by “burden” you mean suing the companies collectively.
