This comes in the middle of the ongoing Epic v. Apple trial, where Epic is trying to prove that Apple does the same with its App Store. > Let's begin with Valve's class action, which was filed by Wolfire Games on April 27th in the US District Court for the Western District of Washington. A couple of days ago, Wolfire CEO David Rosen wrote a detailed letter to reveal exactly why he is joining the lawsuit. In short, he believes Valve is using its dominant position to enforce game developers to sell their titles for the same price on Steam and any other competing store, threatening to remove the game from Steam if a developer opts to sell it for a lower price on, say, the Epic Games Store or even their own store.
