"Helldivers fans – we’ve heard your feedback on the Helldivers 2 account linking update. The May 6 update, which would have required Steam and PlayStation Network account linking for new players and for current players beginning May 30, will not be moving forward.
We’re still learning what is best for PC players and your feedback has been invaluable. Thanks again for your continued support of Helldivers 2 and we’ll keep you updated on future plans."
Mojang strategy
Just FYI, Mojang has completely locked down all accounts that did not migrate, and they are literally impossible to retrieve.
They did give people 3 years of advance notice that would happen, to be fair. Much better than the one month warning this would have been.
