IIRC the rule Mastercard cited was so vague that trying to workaround it almost seemed potentially pointless. It was basically a blanket "we think it makes MasterCard look bad so we end our relationship". Anyway, debit cards are still Visa/mastercard so using them as cash has the same problem. I was thinking they could just use Steam gift cards but since those are often themselves purchased in stores or with credit cards it seems to just push the problem a little further away.
I believe Steam did support bitcoin at one point but decided to end usage over because the price fluctuations made it to unpredictable on their end. Maybe the landscape has changed though.
