JOSH LIPTON: Apple dealing a blow to Epic Games. The video game software company saying Apple terminated its developer account preventing the development of the Epic Games Store for iOS. Here with the details is Yahoo Finance's Dan Howley. Dan.

DAN HOWLEY: That's right, Josh. This all comes down to what's known as the Digital Markets Act in the European Union. Basically, it establishes that there are certain key players in the technology space. And because of their size, they have to allow for certain capabilities for other companies.

And so for Apple being a key player, they essentially have to allow third party apps to build third party app stores. They no longer have to rely on Apple's App Store as the sole place to download apps. Now Apple and Epic have had a tumultuous relationship, to say the least. Apple pulled the game "Fortnite" and Epic's ability to develop games for iOS after Epic in a kind of showdown with the company over pricing for apps sold through its App Store went ahead and changed prices on its own and allowed a third party means of purchasing apps through the App Store.

All of this is to say they don't like each other. And now Epic is claiming that because of comments that CEO Tim Sweeney made regarding Apple's upcoming changes to the App Store in Europe, that is supposed to abide by that Digital Markets Act, the Apple has gone ahead and pulled the ability for Epic to actually go ahead and build its own third party app store and put games on iPhones.

And so this is a larger problem that Apple will have to potentially deal with when it comes to the European Union and European Commission as far as antitrust goes. It's clear that Epic is not going to stand by. It's clear that Apple is not going to abide by Epic kind of I guess rankling them. And so now we're going to have to see what happens when the two come to blows.

JULIE HYMAN: And what does this mean for Epic in the long run?

DAN HOWLEY: Yeah. I mean, look, Epic hasn't been allowed to sell "Fortnite" on iOS for a while. They were going to be able to do this again, in Europe at least, not in the US, nowhere else, but in Europe in particular. And so it means that there's a loss of potential revenue here that could impact them over the long term.
