A KEY POINT: “The Seuss cancellations also illustrate how a disappearance can happen without a legal ‘ban’ being literally imposed. One day, the Seuss estate decides to self-censor; the next, that decision becomes the justification for eBay to delist used copies of the books. In a cultural landscape dominated by a few big companies with politically uniform management, you don’t need state censorship for books to swiftly vanish.”
