Yeah? The majority of the IPs of games sold on GOG are still owned by someone that isn't CDPR and they could cancel whatever agreement they had to sell their stuff on GOG. Seems highly unlikely tho, since almost none of them cost anyone anything to keep selling as they don't do anything online or, if they do, is P2P stuff or dedicated servers the players themselves run. The games that get killed generally have some kind of always online component and the publishers simply don't want to pay for the servers anymore, nor do they want to spend time retrofitting them to not need those servers to be played.
