Imagine this would be the case for physical stores and only 2 companies in the world could decide what products you are allowed to sell. You start a coffee shop and 1 day later a representative of company X walks in and shuts down your entire store because you "violated our conditions but we won't tell you which one. You can beg us to reopen your store but first you have to tell us why you didn't violate our policies".
This sounds like a dystopia. And yet it's already reality in the app world.
