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.

If a bad app that isolates all of its actual functionality into an expensive subscription mode isn’t a scam, it’s at least a rip-off, and really walks the line between scam and terrible product priced outrageously. At which point it might as well be a scam, because there’s clearly dishonest marketing involved.

The regulation is that an egregiously bad app should not be allowed to be present on a top grossing list. Apple should inspect this case and allow dissatisfied customers to receive refunds accordingly and swiftly.
