>If people find their app, like what they see, and are willing to pay the price, what is your objection exactly?

My more general objection to your question is that I don't consider individual preference, or individual choice, or individual action beyond criticism, just because the individual is "fine with it".

People can "find a product, like what they see, and be willing to pay the price", and the purchase could still be stupid and deserved to be called as such, and the price could still be highway robbery and be deserved to be called as such, and the product could still be subpar/average/bad and be deserved to be called as such.
