That's quite bleak because PS Plus isn't as cheap as it once was, and if you are a subscriber, this recurring charge was at least a way to reinvest back in the ecosystem. Annoyingly, you will also need to manually log into PlayStation Stars via the PlayStation App or online and review the TOS, or you will be "considered a cancelled member".
Sony, as ever, remains savage, coldly offering its subscribers a choice: "[PlayStation Stars members must] accept the updated Terms of Service to remain a PlayStation Stars member, or decline and cancel your PlayStation Stars membership. If you do not make any selection, you will be considered a cancelled member until you accept the updated Terms of Service."
