You are saying that as a paying customer, one is not allowed to question any product or service offering they pay for (or even will potentially pay for as a potential customer). One is not allowed to suggest improvements. One is not allowed to state that if the company would modify the offering in some way, then they would again become a paying customer. One's only choices are to pay for the product/service as is or walk away and keep quiet.
One is also not allowed to mention to friends/acquaintances/colleagues that they are dissatisfied with the overall value of a product or service, or indicate that they do not believe the overall value to be worth it. As before, one's only choices here are to give good recommendations of the product/service to others or to not say anything at all.
"Take what we offer or walk away quietly and never speak of this again, those are your only choices."
This is essentially what you are saying. Are you sure that is what you want to be saying?
