That's not the point. What I was trying to say is that a bad app doesn't have to be a scam and that pricing or rating isn't a reliable indicator for that.

Again, the fundamental question at the root of this issue is who's to decide what things should cost? Since when is it illegal to offer bad products that cost too much? That's a negotiation between creator and potential customer. Not buying a product that doesn't meet your expectations or budget is perfectly fine. This doesn't need to be regulated.
