If I'm right, this was a fantastic job of link-bait. Users, especially parents, hate in-app purchases. But that's the way the app market has gone for now. So far I've been able to resist but except for educational apps (schools have the worst time paying for IAPs), I'll likely be doing a lot of freemium apps. So this hits a sweet spot to vent hate for IAPs and the freemium model. Great job guys.
I've noticed a lot of games in the Mac App Store are starting to have a single "unlock full game" IAP. These I really like. The good ones have enough content to show the nature of the game, get me hooked on the mechanics or story and lead directly into the single unlock.
It's a classic shareware model and results in my willingness to pay more for games because there's much less risk. The good ones also are very explicit in the description on the App Store that it is a first level/trial with IAP.
Like old school shareware, where you got the first episode to play through and then could purchase the rest of the game for a small fee.
As for the guy's situation it sounds like they need some more nag screens and easier ways of sending them money. (Well it is currently a lot easier than the old days of shareware, no envelopes to fill out, just a button to press.
Yup. For what little it's worth, "IAP" is a big red flag to me, a warning that the "free" app will prove annoying and/or expensive. I'll usually not download any with it, having learned the hard way (right or wrong) that at these prices it's better to pay the couple bucks up front and get the full clean app, than get "free" and have to wrangle with brokenness and intrusive ads and still end up having to pay.
Sounds pretty dysfunctional. Surely, being able to try something for free before buying it is a positive thing? A shame that it's being done badly then.
