This is missing the point. Can I expect to always be able to remove DRM from any ebooks I might want to buy in the future, no matter what the platform vendor does? Obviously not - that's not a "trivially easy" operation in any real sense. "Just remove the DRM" is always a band-aid and a last-resort, not a real solution.
