The Steam executable itself is a DRM system, as far as I am aware there is no way to download via the website as there is with GOG (or Humble's DRM free options or other DRM-free sites), so personally I don't consider Steam ever DRM-free.

GoG doesn't let you download without a username and password tied to a license. Neither does Humble.

The App is just a cdn api wrapper.
