CDPR trying to increase their profits by not dealing with GMG is fine. (Though a bit funny for a company which likes to present itself as pro-consumer)Well even EA did the same thing with Origin. In particular, they don't allow STEAM to sell their games. Viewing as a publisher, I don't see the problem with that. Why reduce my profit when I have my own store to sell games?
GMG reselling legitimately obtained keys in response is also perfectly fine.
What's wrong is CDPR then engaging in a smear campaign.
