I don't think many people are against prohibiting and/or restricting the use of dark patterns, and trying to push back on absolutely horrific user experiences. I don't think anyone is arguing that apps should be able to target and trick children into spending money, especially with the current "The walled-garden is to ensure everything is safe" argument.

There is a difference between "Your app doesn't exactly follow our branding rules and you have a link that goes to a non-app web page", and "Your app is specifically designed to trick people into spending money and to spy on children".
