Let’s be clear, the reason is absolutely greed. If Epic were charged 0% to be on the App Store and for transactions (minus fees to CC providers, etc), they absolutely would not have sued.
I see 2005-2025 as a period of appification to counter the complexity and sprawl of the old internet (which was fine and interesting and simple enough for us, but not everybody).
>2025 will see the best of both worlds (we will still easily install apps, easily see permissions shared etc. - But will also get our freedom back, companies won't have 30% revenue taken, etc.).
Optimistic, huh.
