>They shouldn't have sold the games on Steam in countries where PSN is not available

yep, as simple as that this would have made the situation much better. Game would have gotten lower scores and player base overall. Doing it now and like this leaves the feeling, that they got enough money from sales and now they want to bring some traffic to psn

Yes this is a puzzling part of the story, for sure. The handling of the situation overall is pretty poor (also for instance the community management response was pretty stupid)

Even if they did that at launch, I can still smell backlash.
