App Store launch was late 2008, something like 15 months after the iPhone launched, which is to reinforce your point. At the time the ground rules were not at all well established, only what was in that first policy document developers had to sign and Apple hadn’t yet accounted for any of the edge cases developers would come to discover.

App Store descriptions were also more prominent at launch than they are today. The developer did nothing to obfuscate what it was nor to try and cheat anyone. The price was there, the description was there. It was exactly what he advertised.
