And how much worse would they have sold if they weren't DRM free? You can't assert they would have sold better without actual data, and there isn't any available. But in the case of cyberpunk specifically, made by cdpr, the company behind gog, I can safely say that if they had DRM they would have instantly alienated a significant portion of their fan base.

That's not how data works. It doesn't say anything but what it says. You're making inferences, which sure fair but until there's data specific to your inferences (there isn't) you can't say that. You can say denuvo cracks in the first week in the case of some 90 games resulted in up to a maximum of twenty percent loss of sales. It is an important distinction. And the massive success of DRM free titles also goes against your assertion.
