Epic CEO: Apple has lost all sight of the tech industry's founding principles

It's all kicking off between Apple and Epic again, with the latter's CEO taking to Twitter to accuse the former of losing "all sight of the tech industry's founding principles".

This came after Apple sought damages for breach of contract. The move came after Fortnite added an in-app purchase system that bypassed the App Store last month. It's been a constant legal spat ever since, with Epic CEO Tim Sweeney taking exception to the latest claims coming out of Cupertino.

Sweeney linked to an Engadget piece that quoted Apple saying that Epic's lawsuit was "nothing more than a basic disagreement over money". Sweeney disagrees.

″Epic's lawsuit is nothing more than a basic disagreement over money," the tech giant said in its filing with the District Court of the Northern District of California. "Although Epic portrays itself as a modern corporate Robin Hood, in reality it is a multi-billion dollar enterprise that simply wants to pay nothing for the tremendous value it derives from the App Store." Apple revealed in the filing that Epic has made more than $600 million from the App Store.

In fairness to the Epic CEO, he has been making a point of late that Epic is doing this for all developers, not just the multi-billion dollar company he works for.

Whether that's actually the case or not, it's clear the relationship between Epic/Sweeney and Apple is done at this point. Epic has been on-stage at Apple media events – that's probably not happening again any time soon!
