Scams are fraudulent. If you see the latest iPhone and buy it, even if you don't "need" it, and the phone is exactly as what was advertised, then you were not scammed.
If you can't afford the new iPhone, and yet you bought one anyway, perhaps sacrificing against a food budget or a clothes budget or by going into debt, then that's an inability to delay gratification. It's a personal fault, and something to work on. But you weren't scammed.
Religion is more complicated. You could probably argue, with some success, that religion in general is not what's advertised. More so with the WT, I imagine.
