At what seams would you break Steam at? In this day and age those are just app store features. Is there anything you listed Sony, Microsoft or Apple don't have?

I do understand having a Steam library would make it harder to switch but most of us have a few GOG games and collect Epic free games as well (though, I haven't even looked at the free Epic games since Christmas).

People even download a launcher like Hero Launcher on the Steamdeck to run games from other stores. We have the freedom to use Steam in tagent with other stores and we do. You can buy a game off GOG and add it to Steam to launch it.

Steam is simply the better product, hands down.

Edit: To prove that I see your point but just don't agree with it: Here is a quote from an ArsTechnica article about a judge viewing Steam as a monopoly.

Despite those changes, Judge Coughenour once again dismissed Wolfire's argument that Valve had engaged in "illegal tying" between the Steam platform (which provides game library management, social networking, achievement tracking, Steam Workshop mods, etc.) and the Steam game store (i.e., the part that sells the games). Those two sides of Steam form a single market, the judge wrote, because "commercial viability for a platform is possible only when it generates revenue from a linked game store." What's more, the suit has not shown there is any sufficient market demand "for fully functional gaming platforms distinct from game stores."

Does this judge expect me to buy a game from Epic which is missing features and then pay Valve a fee to contact the developer through Steam? Will Epic cheapen their price by 30% so I can "enable Steam features." This would be unprecedented. I cannot go to Amazon to return/complain about a product I bought from Walmart.
