I will just copy what I said in other thread.
Steam is not just a store. Over the years Steam became a platform. Epic and Bethesda Launchers are so barebones, that they can only be called store fronts. As a consumer I choose whats best and most convenient for me. Sure, supporting dev is cool and all, but I won't make a decision to use inferior platform just because dev will get a bit more money from me. It's like having an option of playing Borderlands 2 on PS TV or PS4. PS TV version is serviceable, but Borderlands 2 on PS4 is indefinitely better, so why would I choose the former? When Steam wanted devs to release their games on Steam, they didn't bribe them. They didn't tell them that they couldn't release the game on other stores if they wanted to put a game on Steam. Steam is more open than most people think. Devs can generate as much game keys as they want for free and then sell them elsewhere. Steam gets 0% share that way, but they still allow it. Where do you think keys from Humble Store and other stores come from? Steam didn't fight with competition by making 3rd party games exclusive. They fought them with features that make Steam a platform. You have Big Picture Mode, Achievements, Dedicated forums for every game, Community page for every game, Cloud saves, Family Sharing, Refunds, Universal Controller support, Steam In-Home Streaming, Proton, and the list goes on! You get all of this for free and Steam is doing this to fight for the consumer. How many of the mentioned features those other stores have? Most things I mentioned are made for convenience. Want to play Rage 2 on two computers? Have fun manually copying saves every time you switch computers. Want to refund a game because its riddled with bugs or it doesn't work for you? Good luck. You want to use your gaming PC on TV sitting on a comfy couch with a controller? Not going to happen without Big Picture Mode. You want to share that new Fallout game you just bought with a friend? Yeah, no, you can't do that. Now image we actually accepted that reality and every publisher release games on their own store fronts. You have like 8 launchers, so with 8 launchers comes 8 friends lists. You have a friend that also plays on PC? Cool, you have to add him to friend list 8 times. Not the most terrible thing in the world, but lets be honest - it would be super inconvenient and irritating. And imagine how many launcher updates you would have to deal with. Look how many friends lists you would have to browse through to see if your friend is playing something.
If you only play single player games or you don't care for all those features and you just want to buy a game and just play it, then cool, I guess multiple launchers doesn't change much. But you have to aknowledge that whatever Epic and Bethesda is doing right now is not competition. You know what would be best for consumer and developer? Options. Want to buy it on Steam or Epic Store? You choose. CD Projekt is an example of doing things right. They have their own platform - GOG and yet they released games on Steam too. How did they try to attract people to buy their games on GOG? By making them cheaper than on Steam. That's what I would call competition. If Epic and Bethesda want to compete with Steam, then they should either do it GOG way or they should expand their launchers with features that will benefit players.
PC gaming is open without epic and Bethesda launchers. You have MANY stores that you can get games from and that compete with steam. The cool thing is that when you buy games from those stores, you actually get Steam keys, so you get all the benefits that comes with it. I have nearly 200 games on Steam, but maybe 10 of them were bought directly on Steam. I got the rest of them from various stores.
Edit. So when people say "What's wrong with pressing a different button to launch game" are missing a point.
