That DRM is currently Steam. Adding another launcher only adds to the headache PC users have to deal with: EA, Ubisoft, Rockstar, etc. Horizon ZD currently sits on GOG without DRM. Unfortunate that it's the only one but it's possible.
Just because it exists doesn't mean we should put up with it.
People gave Larian shit for their launcher so they added a launch option to skip it. It wasn't DRM, it was an added headache and they recognised that.
I don't understand why people are willing to let companies do shit like this just because their sacred cow is on Steam. Have some goddamn principles.
