DRM is optional for Steam games, I think that's a pretty good balance between the interest of game developers vs the interest of user, it's an issue between users and game devs, not between users and Steam.
The more important point is though that the Steam DRM is hassle-free for the user. For instance games (with macOS ports) I already bought for PC I can also just install on my Mac, with save games automatically shared between the two. I don't have to buy a separate Mac version (as would be the case with Xbox vs Playstation), nor do I need to pay extra, so there's no incentive to pirate the Mac version.
DRM could also be executed in a way that makes it impossible for companies to claw back the content. DVDs use DRM and all it does is restrict what devices can access it, but it can't be retroactively clawed back. Consumers understanding when that is the case is the problem. They just assume it can't be clawed back or they just think it's very unlikely, and only get mad when it happens. Unexpected restrictions in content is a centralized platform thing in general and can happen with your own content on any cloud storage provider for example, it isn't necessarily a DRM problem.
