Anakin-Skywalker: Let me know your thoughts
Most importantly, they could stop lying. GOG used to excel at open communication with their customers many years ago. CDPR might try that, to regain lost trust. Openly apologize and be honest and forthcoming about the state of the game and about all their decisions.
So much for CDPR. But what could GOG do to regain lost trust?
1. stop selling games with partial DRM (Absolver, NMS, ...)
2. stop selling games with full DRM through Galaxy (Epic-deal)
3. stop selling Galaxy exclusive 'incentives', like for Cyberpunk 2077. Anything 'Galaxy exclusive' requires Galaxy by definition and is therefore a breach of the 'always optional' promise. Make every offline-installer version equal to the Galaxy version, as promised.
4. start selling Devotion or at the very least be honest about the reason why they don't sell it. The "many gamers" lie is just insulting.
Those are things that they COULD do. Other things, that I would like them to do, but which at this point aren't feasible anymore is:
5. force all devs to add drm-free multiplayer to those games that don't have it so far (LAN or direct IP or dedicated server)
6. stop distributing GWENT through GOG or make it optionally DRM-free (with a fixed set of cards, microtransactions won't work, of course)
