Which they don’t do. Their platform has very few features, and doesn’t even have a cart. (Well last time I booted EGS like a year ago).
They have almost no features and of the features they do provide, none of them are great. Their only “feature” is operating at a loss, subsidized by megacorps, for many years like Amazon to gain a bunch of market share.
Luckily for gamers, steam already existed so they couldn’t corner the market and enshittify the entire industry like amazon did.
