Good Old Games (GOG), a subsidiary of CD Projekt RED, is releasing an online gaming manager similar to Steam and Origin. The difference is that everything about it is DRM-free and completely optional. Galaxy will manage game updates, provide achievements, and host communication between friends… if you want. If you don't? That's okay. Have fun.
Obviously, their most popular competitor is Valve. Steam has a history of being nice to their customers and erring on their side. GOG, historically, takes it to the consumer-friendly extreme. If it lives up to their statements, this is no exception. The hope seems to be just that people will remember GOG more often and have more happy customers.
Basically, most platforms are give-and-take. This is take what you want.
When will it launch? What will it look like? Who knows. We will get more news this year, which suggests that we will not get the software until at least next year. Hopefully they will take their time and get it right. I mean, it is not like they need to rush. It is not a mandatory DRM platform – it is not a DRM platform at all. I do expect they will try to target The Witcher 3's launch window (February 2015) for marketing purposes, though.
