I didn't start buying ebooks from Amazon/Kindle until I realized it was relatively easy to break its DRM. I've never used the files anywhere else but I keep a cracked copy of every purchase just in case. That old story about "1984" being removed gave me too much of a negative impression.
Some examples of the lengths they go to:
- They used to have a desktop app that allowed reading offline. Not anymore. They're phasing it out in favor of their web reader which has no offline reading functionality. Presumably because people were cracking the DRM there.
- Their Android app detects root/custom roms and disables itself and starts spamming you with a new browser tab every few seconds, even if you don't try to open it at all (I have no idea why this is even possible on Android). It doesn't just use Android's built-in SafetyNet APIs either, it uses some custom methods that somehow managed to bypass Magisk's root hiding feature until version 18, when I discovered that it finally started working. But soon after that I found my account mysteriously locked, and upon contacting support it sounds like they were able to find out I was running under root somehow, and reinstated my account with the caveat that the next time they catch me my account will be disabled for good. That was the last straw for me, and I vowed never to do business with them again.
With that said, I do hope someone who's more well versed in the dark arts of reverse engineering than I am could take a crack at breaking the DRM in their Android app or Desktop app (they still post a really old version on their site, not sure if it's still usable) dump their entire library on a torrent somewhere and show them the futility of their ways. I honestly think their DRM only survived for so long due to sheer obscurity because they have a such a limited audience and not enough smart people are interested in fucking with them. I'd love to have some means to liberate the library of books I've already regretfully purchased on there (they lured me in with their frequent sales and rewards program).
They have an English site too if language barrier is an issue: https://global.bookwalker.jp/
