Nobody is saying your app should be entirely free. They're saying it should be opt-in after the free trial, and that you shouldn't be collecting payment information until people are choosing to pay for your product. That's good practice in any domain; it's especially important in the field of mental health care. Many lawyers offer a short consult before they start charging. When we have work done on our house most contractors will provide an estimate and a brief discussion before charging anything. When we go to a store we can look at things before we decide to buy them. A free trial for an app is along these lines; it's not saying your product is free, it's saying people can check it out enough to make an informed decision about whether they want to pay for it.
