Eligible libraries, archives, and museums have a few exemptions to the DMCA’s anti-circumvention clauses that aren’t available to ordinary citizens, but these aren’t unique to the Internet Archive. For example:
Literary works, excluding computer programs and compilations that were compiled specifically for text and data mining purposes, distributed electronically where:
(A) The circumvention is undertaken by a researcher affiliated with a nonprofit institution of higher education, or by a student or information technology staff member of the institution at the direction of such researcher, solely to deploy text and data mining techniques on a corpus of literary works for the purpose of scholarly research and teaching;
(B) The copy of each literary work is lawfully acquired and owned by the institution, or licensed to the institution without a time limitation on access;
© The person undertaking the circumvention views the contents of the literary works in the corpus solely for the purpose of verification of the research findings; and
(D) The institution uses effective security measures to prevent further dissemination or downloading of literary works in the corpus, and to limit access to only the persons identified in paragraph (b)(5)(i)(A) of this section or to researchers or to researchers affiliated with other institutions of higher education solely for purposes of collaboration or replication of the research.
This exemption doesn’t allow them to publish the content, though, nor would it provide them immunity to takedown requests, if it did.
These exemptions change every three years and previously granted exemptions have to be renewed. The next cycle begins in October and they started accepting comments on renewals + proposals for expanded or new exemptions in April, so that’s why we’re hearing about companies lobbying against them now.
The article explains the infographic and adds a lot more context.
The amount of arsenic depends on location - if you’re in a region that has standards on arsenic levels, like the EU, UK, or the US, then you’re probably fine, but the levels may be higher than what’s considered safe for children. This method would allow you to reduce the levels by around 50%, and since the levels for children are a bit under half of what’s acceptable for adults, that’s likely to make it safe for them.
The time savings are relative to other methods for reducing arsenic content, like cooking it with excess water (like a 12:1 ratio) and then discarding the excess, as this method allows you to use a rice cooker for the remaining time and to cook with a much smaller water:rice ratio, even accounting for the discarded water.
