A friend asked me to help her with an ebook she had purchased from which she could not copy any text. It was protected by DRM. It seems that printing it to another PDF file from Okular can do the trick. Don't ever do that, as it is illegal. I did not try to do it, of course. As well as I did not try to convert it to PS and then back to PDF, because it had never worked for me before with other kinds of restrictions. This is knowledge you should never acquire nor share with your followers.

@xiroux I hear the worst of it is the Apprentice Alf's DeDRM_tools!

It can be added as a calibre plugin - so check your plugins to make sure you're safe! It should never be used, as it can break all kinds of DRM from epub, pdf and even mobi... and who knows what this can lead to‽

Stay clear from Apprentice Alf, Apprentice Harper...and any other apprentices, just to be safe!

@FredBednarski @xiroux It's not even worth it to be honest, specially if they have adobe DRM. I mean you would need to download the adobe digital editions software, validate the DRM and download the epubs, install the deDRM program in calibre, and drag the DRM epubs there. Not worth it at all and probably you don't want to do any of that.
@FredBednarski @xiroux Not to mention that it sends the wrong message that DRM is garbage and user hostile, which is obviously not.

@FredBednarski @xiroux i have a theory that ebooks have intentionally terrible drm to keep both customers and publishers happy
i can't think of any reason for why it's so impressively awful compared to literally all other drm

@xiroux Calibre tiene un plugin que quita el drm de Amazon pero no lo uses que es ilegal.

@Stanislaus Grumman Tell your friend to return the book and request a refund because it does not work. The only way the stores and publishers will know that DRM is hurting their legitimate customers is to tell them. While bypassing the restrictions is easy, doing so also don't give any feedback to the publisher or the store.

@harald That's not a bad idea, but I'm sure they do know the hurt it causes.

@xiroux @harald Yeah, they probably do. The problem is, if customers don't complain, that means they accept it and publishers can keep doing it 😕

@Esteban Manchado Velázquez @Stanislaus Grumman Tbh, I don't think they do. The shops often don't have a choice. The publisher is sweet talked by the DRM providers about how it prevents piracy (it doesn't) and secures income for the artist/author (it doesn't). I've had to argue at length with both shops and publishers to get a refund some times. They struggle to even understand the concept that not everyone can read/play the content because it depends on proprietary software that's not universally available.

@xiroux I, too, would like to formally register my objection to this practice. Despite almost all DRM systems falling back to open systems very early on in their pipeline (usually well before the font rendering stage, and almost never afterwards), usually in ways that can be hooked with basic debugger skills – even when the DRM software itself doesn't provide a way to easily bypass the ethically-mandated rights protection, as in your case – it is your moral obligation not to do so.

Don't tell anybody they could published books without DRM or formerly protected by DRM on the internets Genesis Library for no cost. This could hurt the industry living of selling us good backup solutions for our valuable DRM protected public knowledge. Not to think of how harmful this could be in case of a publisher or DRM provider shutting down their well respected services.

@xiroux Never heard about this DRM thingy, probably because it is soooooo easy to use that it blends in to the background and does not cause aaaaany problems whatsoever.
