My girlfriend has the ability to slit my throat at night without me having any way to resist, but I still think being around her is less risky than, say, walking across the freeway. A hopeless situation that is extremely unlikely to occur is less of a risk than a slightly-less-bad situation that is very likely.

In practice, it seems like the difficulty of getting eyeballs and converting them into sales is generally much more likely to kill your app than having Apple reject it. Optimizing for the latter case is not rational unless you have a strong reason to believe your app will be rejected.

:O

Cohabitation: it could be fatal! Best to be avoided.

I wish I could say the same.

Apple has removed people from the app store and basically put them out of business, and no complaints or legal issues were an issue too.

Because you don't have to accept credit cards or enforce licenses? It is the least resistant path from someone's bank account to your bank account. The customer doesn't even take their credit card out of their wallet. Multiply that by the chance that they will accept your app (high), and you have good expected returns.

As much as I want to sell offline web apps to any platform, that store doesn't yet exist.

I think Apple could absolutely make a killing if they'd allow people to pay for other things with their iTunes account.
