It's not that radical.
My favourite distribution is GOG.com because I can keep offline installers forever on my floppy CD DVD hard drive SSD without worrying about DRM, forced updates, or mandatory social/store clients.
If that's not feasible, something like Il-2 GB's standalone installer is a reasonable alternative.
To me, it's about control and the ability to avoid unwanted software required just to play a game.
That said, if Steam is the only viable option for the developer, so be it. It's not the end of the world.
