I doubt Apple is "incentivized" to allow this as the poster claims. Clearly it makes them look awful. Apple is the only company who's been able to convince users to pay for client-side software. Android is mostly full of "free" ad-supported apps. Prior to smart phones, users generally could not be relied upon to buy software. Now, you need to break your banking apps if you want to side-load anything, and it's just easier to buy apps. This has greatly contributed to investment in software development IMO. I do want more freedom to develop on iOS and I also understand why they have limitations. It's because they don't want scam-apps to reach customers.
