So, at first install, I actually linked my account to a PSN account that I knew was banned due to a charge back on an unwanted purchase. At the time, I figured if I discovered that I can't play because my account is banned from PSN, I'd just refund on Steam. I feel I'll be very justifiably pissed if my account is now banned from playing retroactively, long after the refund window.
This is the point of contention I am curious about. If Sony can be the one to kick you off the game that you bought on Steam and you don't get refunded for it, I will review it negatively. Let me know what happens after the update forcing PSN.
