or, of course, stop developing apps. If this is actually a common problem for app developers, then few people will go into this business, and the supply of apps will drop. That will then tell Google/Apple that this is actually a problem that they need to deal with. All businesses have risks. At least these risks you know about beforehand (a <1% chance that your app developer has been shady in past and will get your account banned). This is actually a pretty small risk compared to the >99% chance that the app will sink like a stone in the sea of apps available, never to be seen again, along with every penny invested in it. The app stores are swamped with apps. Every single one of those apps was some person's dream that they spent significant time/money/effort on - building an app and getting it on the store is not a trivial undertaking. The overwhelmingly vast majority of those apps will never make a cent for their creators. From Google's perspective, one less app on their app store at this point is probably a good thing. From the OP's perspective, unless they're seeing significant revenue from the iOS version, writing the whole thing off as a sunk cost and walking away is probably the best plan. Which is ridiculous, I know, but logically true.
