- Particular illustrations have not aged well
- The content itself nor Dr. Seuss can be accused of malice
- The offending content is not really a high risk of perpetrating future malice
- It's completely within the right of the publisher to not want to profit from these books anymore
But at no point did it seem like anyone made the point that you can't read or enjoy the book with your kids!
I think the mistake was the publisher should have just slapped a statement in the beginning, or better yet, just released them all into the public domain. Instead, it seems like they unwittingly triggered an unwritten social infrastructure we have created called "cancellation".
