git checkout -b noDRM FETCH_HEADWhat does kindle and other proprietary DRMs offer? none of it.
What do companies adopting Readium LCP offer? all of the above.
The original https://github.com/apprenticeharper/DeDRM_tools is still open, everybody can use it, Amazon, Adobe, B&N, Kobo don't bother, so it can be used, updated without bits of Readium LCP. LCP which is moving in the right direction IMO: being able to give an ebook to a friend by simply giving the password is great.
Plus, why do some people want to keep and share with the world ebooks they had for free from a public library: they totally crush the only solution which makes litterature available to everyone: if this spreads, libraries will not be able to get ebooks from major publishers anymore. Is it what they really want?

The README says this:
> Note that DRM can only be removed from KFX format files downloaded with Kindle for PC/Mac 1.26 or earlier. Amazon changes the DRM for KFX files in Kindle for PC/Mac 1.27 and later.
KFX is different from older versions in that the file is tailored to the device it is downloaded on. If you download with the Kindle for PC, the file is optimized for your big, high resolution screen and isn't going to be great on an eink device.
There are no cracks that work with the KFX files extracted from the Kindle reader.
Which can be removed: https://github.com/apprenticeharper/DeDRM_tools
Simply git clone https://github.com/apprenticeharper/DeDRM_tools/ and then:
python2.7 DeDRM_tools/DeDRM_plugin/k4mobidedrm.py \
-k ~/.local/share/wineprefixes/kindle/drive_c/users/*/Local Settings/Application Data/DeDRMPrefs/kindlekey.k4i' \
~/Documents/My\ Kindle\ Content/book.azw .
python2.7 DeDRM_tools/DeDRM_plugin/ineptepub.py \
adeptkey.der book.epub book_dedrm.epub
You go to amazon.com/myk, switch to the Content tab, three dots next to the book, Download & transfer via USB. You then drag-and-drop them into Calibre with this add-on set up: https://github.com/apprenticeharper/DeDRM_tools
There's some initial setup required to get your decryption key (easy if you have their e-reader — just enter the key you'll find in device info, slightly complicated if you don't), but once that's done, the friction for decrypting ebooks is pretty negligible.
You'll have to convert them to epub or PDF to be able to read them on ReMarkable, but that's as easy as right-clicking a book within Calibre and choosing "convert".
Most of the other ebook decrypters are basically slapping some interface on top of this Calibre plugin and hiding it behind a paywall.
As for books, when I buy them on Amazon I select "transfer via USB" which let's me download it and when I add it to Calibre, the DRM is stripped by DEDRM_tools [1][2] before transfering into the Kindle.

[2] Note that the tool only removes the DRM, it doesn't anonymise the file. It's still associated with your account.
Well, turns out my strategy of de-DRMing Kindle books[0] is more than a good suggestion, just to be on the safe side.
Under my moral compass, after I have purchased one edition of the book, I have the right to convert it to whatever the hell I want.
If you are a programmer, security researcher, artist, or entrepreneur you can make a difference.
1. As an individual: if you understand the methods, contribute to open-source tools that allow individuals to exercise their rights. https://github.com/apprenticeharper/DeDRM_tools (one example)
Artists: Use self-publishing platforms (gumroad, bandcamp, even spotify...) and self-incorporate. Discriminate against giving your business to companies that don't support open, sane protocols. Don't let them exert their power against the populace through backdoor trade deals.
Entrepreneurs: Create new content delivery and streaming platforms that force the transition to digital--rightsholders like to claim that piracy is responsible for their failed economics, though the truth is that they had an artificial market advantage of scarcity. User-generated content has bloomed with the advent of digital, and more consumer choice is a death knell to the traditional monopoly.
2. As a cause: support the EFF, and any politician looking to work with the FCC who understands this issue is deeper than "restricting content," and could undermine the rights of property and security of ownership. Do not trust anyone who does not comprehend the societal implications of critical infrastructure being "security through obscurity." http://apps.fcc.gov/ecfs/comment/view?id=60001303221
The security of your laptop, the concept of personal ownership, and your right not to be digitally inspected at over 40 international borders is at stake.
