“Sony backed this up by claiming it was for player protection, but the Helldivers 2 community wasn’t having any of that and took to orbital striking the Steam page with over 180,000 negative reviews over the past few days.”
Sony decided months after launch that PC players must log into PSN, an account system that does not exist in much of the world. Steam now blocks sales of the game in 177 of its regions. Arrowhead, the studio that made it, says it disagrees with the requirement. Sony sold the game to people it now refuses to serve, and calls the account grab protection.
