If you bought a game and now there's just no way to play it with your friends anymore, that's bad. If you bought a game, and suddenly you are forced to share all your personal information with an additional third party, that's also bad.
But digital libraries do really suck.
This is textbook corporate asshole behavior.
And that's an important point, Helldivers is not an f2p game, it's a $40 upfront game, with cosmetic IAPs on top.
Except it's impossible to create a PSN account in a lot of countires, countries where it was possible to buy and play the game and now it's too late for a refund, so people are stuck with a game they now can't play anymore.
Then they proceeded to gaslight people ("it just takes 2 minutes").
Then they withdrew the game from 177 countries (out of ~195 depending how you count), so people not only they couldn't buy it anymore, but people who had already bought it lost access to it.
It's a shitshow, they completely destroyed players' trust with this.
(Meanwhile there's a holocaust happening.)
By the way, many developed countries that have running water and where people also speak English are affected too (and don't think there is no outrage in other languages), including (but not limited to) Albania, Algeria, Armenia, Bahamas, Belarus, Bosnia, Cayman Islands, Estonia, Georgia, Kosovo, Latvia, Liechtenstein, Lithuania, Maldives, Moldova, Monaco, Morocco and even San Marino, which is basically a neighborhood in Italy.
