The conflict between Epic Games and Apple over fees on the App Store seems continues to drag on. There were signs that peace might break out, but the rancorous atmosphere has returned.

Epic CEO Tim Sweeney has now criticised Apple's position in an incendiary and high-profile tweet. The Cupertino company believes it "owns" all the commerce that takes place on its phones, he says, and considers all alternative payments solutions theft, smuggling or shoplifting.

"It's a crazy, misguided position," Sweeney concludes.

Sweeney's position is that Apple has no right to seize the fruits of Epic's work. Customers who choose to purchase content in Fortnite pay for Epic's creativity, innovations and efforts, he has argued.

More than three years ago, Sweeney criticised Apple's 30% fees, despite the fact that the fees on the Epic Games Store were exactly the same at the time. But the conflict between the companies has been far more intense this year: back in August Apple terminated Epic's account, and a judge has accused Epic of lying.
