Ummm... Developers set prices mate. Not the 'shopkeeper'.
Yes, "mate" is not stupid. Developers also choose to bundle multiple Mac apps together and sell them as a discounted bundle. That's something they'll now be able to do in the EU.
And Developers have had to factor in Apple's steep cut and Apple's future cuts of in-app purchases and subscriptions. In the EU, Developers could cut pricing some because they don't have to cover Apple's cut... make a bit more for themselves as their own shopkeeper (exactly as it works when we buy apps direct for Mac) and not necessarily need to work Apple's cut into subsequent transactions too.
We can doubt this kind of stuff and also believe all of the rampant virus/trojans nonsense some sling too... but all we have to do here is just stand by and watch what happens. This story very clearly illustrates that apps desirable to some- Epic games- will be available again to Apple people... EU Apple people. Will those be the only ones? No. Many apps that Apple turns down for whatever reason will now be able to be made available in a market with about 100M
MORE people than the good old U.S.A.
Will pricing improve? I suggest it will because developers won't have to bake in Apple's big cuts. They can actually charge less but make more for themselves by cutting out the "middleman" who takes a first big cut of every transaction in the rest of the world.
Will app bundles for dirt cheap show up? I suggest it will because that works very well on Mac and it will likely work as well on iDevices.
Etc. Doubt it all if one wishes, but whatever is going to happen- good or bad- is about to play out right before our eyes. It could be viewed like a giant market segment "test" in which we can all gauge the success or disaster in this law being enforced and Apple (mostly) complying with the spirit of it. All of the rest of us- some 93% of the world's population will be removed from any risks we can imagine in this scenario... because we're still limited to getting Apps in the "as is" method.
But in about 6 months, there should be volumes of "updates" and "reports" highlighting the pros & cons of this change and how it all played out. If I was betting, I'd bet big on the overall impact being very much like the overall impact of the very same freedoms existing for upwards of 40 years for Mac: EU people having access to MORE apps, paying generally less (than before) for them, and minimal negative consequences like the much spun security disasters we've read in every thread about this.
