Stories like this from Dash (and others) is a real-living and breathing worst-case scenario... it makes the choice to not participate in this marketplace all the more obvious to me.
The smartphone 'market' is an oligarchy, ergo, it's not really a free market, and those kinds of principled positions just don't hold.
It's pretty reasonable to argue that Apple's arbitrary control of the AppStore is an anti-competitive practice.
If the market were commoditized, like, the choice you have for where you want to 'eat lunch' or 'buy a car' - it would be different.
Can I choose my opportunities? To some extent.
The point I was making is that this rhetorical device of "I need to eat" is used way too often as a euphemism for "I want to make a lot of money". It's used that way because the former statement elicits sympathy and the latter statement attracts derision.
In the context of the original comment, the "need to eat" phrase was used in the context of an app developer. You don't create an app on the app store as a last ditch attempt to feed your family. You do it to make money, and you do it knowing the risk that it won't be successful and you won't make any money. Apple's inscrutable opaque approval process is another annoying risk on top of that, but whether you're going to eat shouldn't be a part of the equation here.
At least Apple only takes ~1/3 of the value of the work you put into in the App Store.
If a particular bit of conduct would be a poor idea if everyone were to do it, that's a pretty good idea it shouldn't be allowed at all.
One example, on iOS WebKit if you flick to scroll, and then "click" (touch) on the screen while the scroll animation is still running, the click event will report a position on the webpage that was as if the scroll had never happened (e.g. you had clicked on the same place on the screen without having scrolled in the first place).
Here is one key tradeoff I see: the App Store brings more visibility in exchange for a cost. This situation accentuates another downside: plug-pulling for intentional or unintentional reasons.
FWIW, I use plenty of apps not on the app store.
