So enabled, in fact, that there's almost no point in downloading an already-made app when you can just trivially tailor-make your own. The builder is massively enabled to quickly make anything they want, for an audience of exactly one.
Combined with the fact that my use cases aren't your use cases, yes, it might be cheaper for me to make my own than to slog though software that wasn't built to serve my exact needs.
You only need to reimplement that 2% for yourself for it to be worth it, not the entire app.
