Ignoring its own policies, Steam stewards
Valve have also reportedly been
issuing refunds to several long-time Helldivers that have logged into Super Earth space for more than 100 hours. Steam policy normally doesn't allow for refunds if a player exceeds two hours in-game, but since the PSN requirement came months after launch, Valve (rightly) seems to be making an exception.
A Helldivers 2 developer recently reiterated that
the PSN change came from Sony, not the talented team at Arrowhead Studios, so issuing refunds is probably the most effective route to getting a message across, as opposed to shouting toxicity at devs. Sony also announced the mandate on a Friday, and thus, has yet to officially respond to the backlash that has escalated pretty wildly in just a few days.
