Epic was always behind Steam, if you like it or not. That Valve tries to assure its independency from other vendors (Microsoft) by creating its own OS and hardware should not be too difficult to understand as a company decision. At the meantime Epic is trying to buy its place in the market with exclusives and free games, not respecting or trying to bend other platforms rules.

I don’t care where you buy your games, but I do care, which companies try to force me to their buggy, unfinished and user-unfriendly platform, for a game I was waiting to be published.

But it’s a preference thing.
