Tesla on Steam!
Actually, a game being on steam doesn't mean that is has DRM! Games don't necessarily have to use the components of the Steam program that makes Steam's DRM work (Steamworks CE).

So there's no issue with Steam and DRM. Big Finish should not have to use another server or GOG.com to distribute DRm-free games.
Heck, Big Finish could even give a DRM-free version to backers as promised, and then have different pricing for DRM-free and DRM-present versions of the game. The KickStarter campaign never said they couldn't do that.
