Eh, I feel eBay has more of a right to ban books than a library. Both are bad, and it’s terrible that society is in a place where book banning is virtuous.
I don't necessarily think eBay should be forced with legal might to sell these books -- but it's a terribly bad look for their company. Book banning has always felt scummy to me, and I always think back to being a child when many in my community participated in Harry Potter book burning events. Book burning, witch burning, it's all mob mentality and it's terrifying.
