 <p>Denuvo is a digital restrictions management (DRM) system that is
 integrated into the code of some PC games, as an “anti-piracy
 solution.” But what Denuvo does, really, is to make the games <a

 <ul>
 <li><a href="https://whyisdenuvobad.github.io/">It
 requires periodic connection to the Denuvo servers</a>,
 even for games that can be played locally. As a result, <a
 href="https://www.pcgamer.com/a-great-day-for-drm-as-denuvo-lapse-renders-tons-of-games-temporarily-unplayable/">
 a number of games became unplayable</a> when these servers stopped

 <p>HP delivers printers with a

 href="https://www.theguardian.com/money/2023/may/10/how-can-hp-block-me-from-using-a-cheaper-printer-cartridge">
 sabotage them by remotely installing malware</a>. The malware makes the
 printer refuse to function with non-HP ink cartrides, and even with old
 HP cartridges which HP now declares to have “expired.”
 HP calls the back door “dynamic security,”
 and has the gall to claim that this “security” protects
 users from malware.</p>
 <p>If you own an HP printer that can still use non-HP cartridges,
 we urge you to disconnect it from the internet. This will ensure that
 HP doesn't sabotage it by “updating” its software.</p>
 <p><small>Note how the author of the Guardian article credulously
 repeats HP's assertion that the “dynamic security”
 feature protects users against malware, not recognizing that the

 <p><a hreflang="ja"
 href="https://ja.wikipedia.org/wiki/B-CAS">B-CAS</a> <a
 href="#m1">[1]</a> is the digital restrictions management (DRM) system
 used by Japanese TV broadcasters, including NHK (public-service TV).
 It is sold
 by the B-CAS company, which has a de-facto monopoly on it. Initially
 intended for pay-TV, its use was extended to digital free-to-air
 broadcasting as a means to enforce restrictions on copyrighted
 works. The system encrypts works that permit free redistribution
 just like other works, thus denying users their nominal rights.</p>
 <p>On the client side, B-CAS is typically implemented by a card
 that plugs into a compatible receiver, or alternatively by a tuner
 card that plugs into a computer. Beside implementing drastic copying
 and viewing restrictions, this system gives broadcasters full power
 over users, through back doors among other means. For example:</p>
 <ul>
 <li>It can force messages to the user's TV screen, and the user
 can't turn them off.</li>
 <li>It can collect viewing information and send it to other
 companies to take surveys. Until 2011, user registration was
 required, so the viewing habits of each customer were recorded. We
 don't know whether this personal information was deleted from the
 company's servers after 2011.</li>
 <li>Each card has an ID, which enables broadcasters to force
 customer-specific updates via the back door normally used to update
 the decryption key. Thus pay-TV broadcasters can disable decryption
 of the broadcast wave if subscription fees are not paid on time.
 This feature could also be used by any broadcaster (possibly
 instructed by the government) to stop certain persons from watching
 TV.</li>
 <li>As the export of B-CAS cards is illegal, people outside Japan
 can't (officially) decrypt the satellite broadcast signal that may
 spill over to their location. They are thus deprived of a valuable
 source of information about what happens in Japan.</li>
 </ul>
 <p>These unacceptable restrictions led to a sort of cat-and-mouse
 game, with some users doing their best to bypass the system, and
 broadcasters trying to stop them without much success: cryptographic
 keys were retrieved through the back door of the B-CAS card, illegal
 cards were made and sold on the black market, as well as a tuner for
 PC that disables the copy control signal.</p>
 <p>While B-CAS cards are still in use with older equipment, modern
 high definition TVs have an even nastier version of this DRM (called
 ACAS) in a special chip that is built into the receiver. The chip
 can update its own software from the company's servers, even when
 the receiver is turned off (but still plugged into an outlet). This
 feature could be abused to disable stored TV programs that the power
 in place doesn't agree with, thus interfering with free speech.</p>
 <p>Being part of the receiver, the ACAS chip is supposed to be
 tamper-resistant. Time will tell…</p>
 <p id="m1"><small>[1] We thank the free software supporter who
 translated this article from Japanese, and shared his experience of
 B-CAS with us. (Unfortunately, the article presents DRM as a good
 thing.)</small></p>

 <p>How pitiful that the author of that article says that there was
 “nothing wrong” with designing the device to restrict
 users in the first place. This is like putting a “cheat me and

 Indeed, it is the acceptance of their unjust practice that teaches

 <p>DRM does more nastiness to published works than merely stopping
 people from looking at and/or copying them. Even when it allows you to
 look, it harasses you in many ways. Cory Doctorow's article presents

 DVDs as an example</a>.</p>
 <p>We condemn the propaganda term “pirate” when it
 is applied to people that share copies. Many of these DVDs are
 made and distributed commercially; in reference to that practice,
 “pirate” might be partly justified. But not when they
 protect users from harassment.</p>
 <p>The fundamental cause of this harassment, and the fundamental
 wrong of the (追記ここまで) DRM in (削除) Cars Will Drive Consumers Crazy</a>.
