Your logic doesn’t work, either BIg wasn’t making any sales and FC only took back the unspent portion of their own loan to BIG, or BIG were making plenty of sales and FC were taking a huge cut in fees.
Big were making bugger all sales, and FC was forwarding cash for customers who agreed to a free video. To release the held money BIg had to then sign that videod customer up to a paying subscription, or find another customer who would sign up.
Basically fc was advancing working capital without any paying customer committed to a purchase.
Not sure how fc come out on top other than through selling the shares they got for free.
