It doesn't matter whether it's unique. I'd find it outrageous if a book disappeared from my bookshelf on a publisher's whim even if the physical book was otherwise unimpressive -- even if, in fact, it wasn't a very good book to begin with. The book is mine. The publisher cannot decide when it stops working. Only a force of nature, like a fire, can take my books away from me.

If you're content in the knowledge that you can buy your e-books again whenever a publisher decides to make them stop working for you, good for you. Me, I'm not happy letting publishers win and trample my rights. In fact, much like the original tweet, I find the notion outrageous.
