Honestly, I think this is a GREAT idea! It'd a bit of a roundabout way, but that might be a good temporary solution if things do start taking a nasty turn. Which, is sadly how a lot of these cases typically go before they get better...
It's ridiculous that these companies think they can control the money we earn to such an extent... And the payment companies are trying to use the "think of the CHILDREN" pearl clutchers as an excuse. On the plus side, this may help shatter their monopoly on payment methods and we'll see an increase in competition...
Regardless, I hope a good solution can be made. These game developers should be allowed to get paid for their work and we, the consumers, should have the right to buy them.
