What is exploitative is the way almost all supposedly child friendly apps try to trick or corrupt children with ads and gamified purchases. My post comes out very explicitly against this, which I presume you read.
I was merely responding to the kind of language you used to describe it. You call it the language of designers and engineers, but I'm sorry, that's not my language! To me, that is the language of commercial entrepreneurs and capitalists and they give me a gag reflex.
I would love for you (and everyone else) to be able to live in a world where you can pursue this kind of passion project without having to worry about “making a living”. The commercial and capitalist mindset is what's standing in your way.
While easy to use softwares are more 'enjoyable' and the dopamine reward is high for small actions, it also prevent to develop some ability and resilience in navigating harder things. When the software complexity increases, users get annoyed and don't use it correctly because they were never exposed to much complexity before. (thinking about medical softwares that require many many actions to encode a patient, finance softwares, etc..)
Now, not all softwares are made to improve one efficiency. In your case, the app allows a children to express its creativity in other ways, which is very valuable also. So I think it is good that the interface and the interaction are easy, the focus should be on the creativity and not on the manipulation.
Professional apps should stay professional and more time should be spent in training power users.
I'm trying not to mix with my own survivorship bias,but I tend to believe that current trends of design remove the existance of advanced users at a young age. The applications are so polished and limiting that you don't spend time trying to do complex things with them.
I find bugs in old apps were a feature for learning. If it doesn't work, you try to understand why. Curiosity is intrinsic to young children, until we remove it by giving them something that never bug or limits their possibilities.
It's odd to see such nonsensical detractors here on HN.
