- the abusers are people who wouldn't buy anyway
- the positive PR will help GOG to increase the sales, as this is a niche platform compared to Steam. Increased sales will compensate the losses
- some people will buy more, knowing that they can try and return. It is likely that they will keep their game, that they wouldn't try otherwise
- the owner of GOG sells their own games on the platform: The Witcher series, Cyberpunk 2077. These games have higher margins than the games licensed from 3rd parties
- I think they want to increase the awareness of the platform before Cyperpunk 2077 ships later this year
