Apparently the fee is going to be refunded if you reach $1000 in sales. So, even from a "costs passed on" perspective, the only thing going on is that people who buy games paying into the fewer than $1000 are paying for the $100. Er. Assuming the sales even reaches the ~$150 required for Steam to even give anything back (you have to make $100 after Steam's 30% cut to get paid, if I understand it correctly)... I wonder how many games even fall into that bracket?
