Which is why I try to decrypt everything I purchase, or obtain a decrypted version after purchase. (The only grey-area exception is if I own the physical copy of the book, I consider it ethical to download the ebook, but this is of course debatable to a degree)

They could easily do what Apple did and leave things un-DRM'd but digitally-signed as having been purchased by someone.
Buying hard copies of a book and the pirating the DRM-free digital version is completely acceptable imo - as long as you buy the hard copy in a bookshop and not online ilk like Amazon.
Most local bookshops also will offer shipping if you’re too lazy to walk there a couple of times/year.
