Just look up Helldivers 2
Short version
Arrowhead developed and sony published one of the most successful live service games in recent times. A potential 2024 GOTY.
Then sony decided to add a mandatory PSN acc link even if you wanna play on steam. It wasn't mandatory at the start. And it's been 3 months since release.
The crux is, only like 70 countries have PSN. So, all the players that bought the game from other countries can't even play the game they fucking paid for...
So players got mad and review bombs followed. And now sony has disabled the game in like 170 countries. That's gonna cost them a lotta money and customers lol
They just fucked themselves in the ass essentially.
