Late night tweet from the official PlayStation X account confirms they will no longer force the linking of your PSN account to your PC copy of Helldivers 2.
People didn't care as much for some reason. They got a free cape and most were happy with that. You also weren't going to lose your Minecraft account for living in the wrong country 🤷♂️
My only complaint is that there was a cutoff date for migration. Even if the migration phase was 2 years long.
Also to keep in mind: both migrations were from one account to another, you keep one account regardless. In the Helldivers case it was going to be 1 accounts to 2 accounts, with 2 distinct entities controlling how you can play (Steam and Sony-Playstation).
