I feel like any other major company with Steam’s marketshare would be far less consumer friendly than steam.
Steam funnels a lot of money into Linux, and Linux is very popular on Lemmy. If you use Linux, you are benefiting from Steam’s success.
Steam is just nice to use, and has good deals. It’s nice to have my games in one place, and I don’t know if any other storefront with as many nice user benefiting features as steam.
