Apple isn't likely to change the app store for devs because devs need Apple more than Apple needs most of the devs. Although devs do pay to be on the app store, I doubt it adds up to much to Apple.
If anything, Apple should be concerned about how the users feel. The facts are that 64% of the users download ZERO apps in a month, go out to 74% and you get 1~2 apps per month.
Most users use a very small number of apps and if you aren't one of those, you don't have much meaning to anyone but yourself.
This is just like the web itself, how many web sites are there? How many hit the radar? As a percentage of all sites, it's what < 5% ?
It'll end up like real life, 1% of the people own 50% of the wealth, but just like the web, anyone that wants to maintain a web page, gets to keep it alive.
Devs created the race to the bottom, we could have stopped at any time and made the lowest price $.99, but we didn't. Mobile ads have lost much of their value, from too much spam, no rules for how many ads to ad blockers.
If a customer can get a good quality app for free, why would they look at a mid-range app? What customer need this many apps? How far do you go down a google search looking for something? 3 maybe 4 pages? More than a million apps is a joke, it was an advertising stunt years ago, now it's a problem for the "look at me, I'm going to be a rich app developer" crowd in a long, long line that the customer doesn't care about.
Sorry if this is harsh, but it's the truth. Remember the gold rush days, now look at the ghost towns they left behind when the gold ran dry.
Yet another bubble, just like DotCom or Housing.
