We aren’t though are we. Look at the example image in the article, it’s a known and established business. Plus all your argument is doing is highlighting how terrible a job Apple is doing at policing and moderating what goes on sale in their own marketplace. If they think there’s that many illegitimate apps and developers on their platform perhaps they should do more about that before demanding more money from legitimate developers?
Apple don’t give a hoot about the safety of your purchase nor the legitimacy of the business practices. Case in point they’ve let the App Store become an unregulated mess of predatory business practices. What was once a nice store front where I could grab a simple app for 69 cents has turned into a cess pit of weekly subscriptions that are there to catch out people, yet Apple are doing nothing about this practice, they’re enabling it, but of course they care about the consumer. An example, the iOS built in clock app is awfully limited, my son wanted to setup some alarms that worked on a two week rota, but the built in clock and alarms don’t allow for that. So instead we scoured the App Store for alarm clock apps that did do this, every single one of them required a subscription for an obscene amount every month (and in some cases every week!) for an alarm clock, and the whole pricing structure is hidden behind small text. They have apps that say they do things they don’t, for example all the ad fuelled scammy apps that say you can play games to earn money, when you absolutely can’t. Or there are kids games with adverts in that are aimed at adults and highly inappropriate. If Apple was doing all this for the sake of the consumers wallet and safety, none of this would be going on in their own house.
