Yeah the 30% cut is insane, and its surprising to me that game publishers tolerate it under steam. But if you look at the PC games market, you can clearly be successful doing the "self publish" route like Minecraft did.

I think just means that valve has turned their DRM into a value-add for the consumer with cloud backups and item trading and such convenience features. And I say this as someone who uses GOG. You look at other competitors like Epic Games Store or EA or whatever and the user interface is bloated and slow, and it is just a pain to use.
