I see you don’t remember the dvd decryption key ordeal.

Fun fact: this is one of the few situations in the US where a prosecutor could claim that this is criminal speech (though I hope and trust they would not, and if it did it would get thrown out by any court respecting the First Amendment). Not a civil issue, like libel or fraud, but the sort of talk that can get a policeman to come and drag you off to jail. If you've ever wondered why DRM is so roundly hated by engine…

I wonder when/where did they make it against the law to even tell anyone. I remember(1) time when law guys made illegal (in US i believe? or EU?) creating software that circumvents certain DRMs, so I made plans to create a txt DRM that would rely on having a preambule like this :

  !copy !save
if there is a !copy the text editor would not allow you to copy the text (like the acrobat reader does), and !save would not allow saving locally (this is even stupider)

The plan was to render notepad.exe and thus whole windows an illegal software because it allows to circumvent the existing DRM. Of course this would make illegal also less and vim, therefore I got scared of the power that lay in my hands, and cease to hit the atomic button.

OTOH this is not DRM nor copy protection. It is just obfuscation.

Eh, I wouldn't be so sure. Reading the DMCA, their code does seem to do what the law says you can't do[1]:

    "No person shall circumvent a technological measure that effectively controls access to a work protected under this title [...]"
with these definitions[2]:

    (A) to “circumvent a technological measure” means to descramble a scrambled work, to decrypt an encrypted work, or otherwise to avoid, bypass, remove, deactivate, or impair a technological measure, without the authority of the copyright owner; and

    (B) a technological measure “effectively controls access to a work” if the measure, in the ordinary course of its operation, requires the application of information, or a process or a treatment, with the authority of the copyright owner, to gain access to the work.
I think (A) pretty clearly applies: the glyphs being randomized in each request obviously counts as being "scrambled", the method used by the author with the hashes clearly descrambles them by matching the provided SVG images to the letters rendered with the book's font.

I'm less sure about (B), not being a lawyer, but I think it's so generic that it does apply: the "ordinary course of [...] operation" of reading the book requires running the apps provided by Amazon. This seems to fit "requires the application of [...] a process [...] with the authority of the copyright owner".

> they made it against the law to even tell anyone. I’m no fan of the DMCA, but I am pretty skeptical of your apparent claim that this post itself is a potential violation of 17 USC § 1201. Obviously the act of circumvention itself qualifies, as does the code in the GitHub repository the post links to, but can you point to any prosecution of someone for a _prose description_ of circumvention (as opposed to actually m…

The post includes a link to a GitHub repository containing code to circumvent the DRM, which probably counts as "technology" and "component".

I think that the link is already gone

https://en.wikipedia.org/wiki/United_States_v._Elcom_Ltd . Found not guilty, but he was charged and tried.

Being found not guilty supports my contention. But that case was about distributing circumvention software, not traditional speech. Obviously distributing software that bypasses DRM is directly addressed by the law.

In USA the trial itself is a punishment.

The thing that killed the download -> crack DRM workflow is that Amazon removed the "download and transfer via USB" option. I haven't bought an ebook from Amazon since. The only viable option would be to buy the book and then pirate a de-DRM'd copy.

For those with an old Kindle, couldn't you download it onto the Kindle and then pull it off of there via USB?

> Being found not guilty supports my contention. Not necessarily. A cynical modern legal strategy is to bombard people with frivolous legal actions that only the well-heeled can afford. Defendants can argue that claims are baseless or frivolous, but to make that argument, they must hire a lawyer and appear in court. To see my point, look at the number of frivolous prosecutions now being launched by ... ah, never mind…

> A cynical modern legal strategy is to bombard people with frivolous legal actions that only the well-heeled can afford Why only describe them and not go for the easiest example: Nintendo.

A lot of the people Nintendo goes after make money with one sort of piracy or another.
