A multiplayer game that's very successful on Steam - but published by Sony - suddenly has a requirement to have both a Steam and PSN account in order to log into the game - a couple of months after the game was released.
As a PC gamer I would be pissed too tbh (on the other hand, it's the same bullshit that Ubisoft pulls for their games released on Steam).
And not just that. They required PSN accounts on countries where PSN is not available (and using a VPN to create it goes against the ToS, and people get banned). So in those countries they have effectively banned you from playing the game you purchased weeks ago.

Though that seem to be enforced less often than people think it is, one Philippine player (a country that did not have PSN) was ejected from Sony's live esports events because of them entering using another country's flag (in this case, Hong Kong - it is a common practice for players in ASEAN region without PSN, such as Philippines and Vietnam, to create an Hong Kong or Singapore account): https://www.carmudi.com.ph/journal/local-player-qualifies-gr...
This is a big deal because PSN not even available in all EU countries. E.g there is no PSN in: Andorra, Estonia, Latvia. In Ukraine for example you can only register PSN account if you own PlayStation.
I think players were already asked to link their accounts since the game's release, but it was optional (in the sense that you could easily skip that step).
