It's the cost of doing business for the seller on the platform. I'm not sure what's the problem here, to be honest. Alternativelly the platform could also charge withdrawal fees, making small withdrawals pointless. Afaik this minimum withdrawal concept has been the standard way of doing business when reselling digital goods. See e.g. the aforementioned AdSense which has been set up this way for 20 years now. The same goes for Steam, once again you have to sell $100 worth of stuff to get paid.
