You know, it's sad that people are eager to pay Apple nearly a thousand dollars for a phone, buy an iCloud subscription to go with it, and maybe buy a MacBook (Pro?); and then content that after all of that money changes hands, Apple still wants to fill 80% of your screen with an advertisement. Then, if it wasn't bad enough, they don't vet the advertised applications for basic legitimacy (meanwhile legitimate apps frequently get caught up in endless nitpicking at submission).
I get why people do it, but it's sad that they do.
