Not to mention some of them have wonderful anti-features, such as physical books that have a handful of online-only chapters that you can only access if you buy the textbook new, thereby reducing the value of used copies.

You'll then appreciate the "Pearson New International Editions" (with a chapter and the preface removed to tank the resale value).

Oh yeah, those are all a real hoot with the lovely almost see-through paper and shoddy binding and printing errors like upside down pages.
