Perhaps off-topic here, or perhaps to be censored, but you can usually find ways to remove DRM if you don't mind breaking laws which are still being tested in the courts and which might provide an ethical challenge. From a practical standpoint, DRM-providers (those who create the DRM algorithms) are constantly making adjustments and changes to prevent available methods from circumventing their DRM-locks.
So to purchase a book with the intent of removing the DRM may work today but may not work on future acquisitions as the cat and mouse game evolves. I don't like DRM because it eliminates sharing that has become inherent in the "added value" of pBooks since the invention of the printing press. On the other side of the coin, pBooks have a long but finite life span depending on the binding and paper quality, something which electronic media potentially lacks if you assume continued ability to read the format being used to store and display the content. It is completely understandable that authors do not want to see their work freely distributed as a potentially infinite number of copies to the entire internet community. With the removal of DRM, the entire distribution would be on the honor-system, something that seems to fail for some reason.
