Cross-play is not a valid defense for third-party launchers shoving themselves in the middle, because a wide variety of games implement it just fine without a whole-ass program between the storefront and the game.Their stupid launcher did, because it is probably trying to do a bunch of things that nobody wants. It broke games that were already working, because it's an additional point of failure.Steam Deck is aiming to create a console-like experience, and consoles absolutely do not allow games to shove launchers in the middle.

It mainly only serves to tell the player, 'hey, you could have bought this from our store! you should have bought this from our store! we exist, and we want to make sure you know that! give us more of your money and data!' It's not that the third-party game store exists, it's that it has shoved itself between the store the game was actually bought from and the game itself, which only negatively impacts the experience.Your non-productive and blatantly provocative reply ignores several facts.
