Don't know anything about how stores work, do you? Before Apple implemented the now-standard 70/30 split, it was commonly the other way around. That is, you'd be lucky if you got to keep 30%.
That's true, but then there was also far less competition, and far better advertising. Your app was very likely to get written up and advertised in national magazines.
OTOH, piracy was a big issue. I used to get waay more questions about my apps than could be accounted for by the number of sold units.
And yet, we don't see that happening on Android. Developers still go to the main store because it offers the most exposure, despite the greatest commission taken. Almost every store takes 30%. Those that charge less have mini viewership.
Not necessarily. See: 10 Android App Store Alternatives
Also, there are region / culture specific Android app stores, from Russian only, to of course multiple Chinese app stores (since Google's Play Store was banned because Google wouldn't bow to Chinese censorship years ago).
The app store also gave everyone low cost apps that did not exist prior. Those who bought software in the 90's know that applications were $50 at a minimum. Of course there were outliers, but on the other side plenty were more than $100.
Not for phones. There were plenty of free apps available, both from carrier stores and from third party app warehouses like GetJar.
Paid apps were however, definitely more expensive than now. A good remote TV viewer might go for up to $30. A navigation app (this was before Google gave away free navigation) could go much higher.
And of course, just as with now, really good apps like aviation related ones, commanded a decent price.
The app store is the equalizer. The concept of getting rich off of it is a pipe dream, but at least you will be considered published and have some walking around money.
I remember back in 2011, Apple announced that $2.5 billion in royalties had been paid out for over 80,000 paid iOS apps.
By then, just Verizon's app store for DUMB phones alone had paid out $3 billion in royalties to the developers of just 18,000 apps.
