Steam is good for gamers. For developers, not so much, but I love being able to press a button, download on any computer a game I bought, and have my saved games on cloud storage. Epic Games, arguably their biggest competitor, has been giving out weekly free games for years because Steam is so good that people don't leave it even with games for free. Built-in mod support, good download speeds, excellent compatibility with gamepads using the Big Picture mode... It's a really good platform to play with.

Sure, it's still a capitalist business and all of that should be nationalized and made public, especially before it inevitably turns to dogshit, but it is a good platform to play on, as of now.
