Coelocanth: You missed this part, then:
As is often the case, these mass settlement schemes do not exist without collateral damage. Aside from targeting many people who indeed downloaded and shared the game without paying,
CD Projekt’s lawyers are also wrongfully accusing people who have never even heard of the game. After all, an IP-address doesn’t identify a person, and Wi-Fi piggybacking is not unusual.
But CD Projekt, who don’t want to bug legitimate consumers with DRM, apparently take this collateral damage for granted. Well, I didn't miss that part, and I still don't see any actual information in that article to suggest that this concluding statement is correct. It's an anonymous blogger stating his opinion, not a factual article written by a journalist, and the fact it's on torrentfreak doesn't change that.
If they want to keep distributing games DRM free, then tactics like this seem perfectly valid to ensure that those using the game pay for it. What concerns me is that they state very clearly on the "about us" section of the gog website that they themselves don't believe in geo ip tracking, which seems a bit misleading if that's really what they are doing.
