That update was likely the result of my prompting. On 23 November (my local time), I emailed several people I knew who owned .org domains encouraging them to renew as far in the future as possible because the .org registry was being sold. Here's a copy of the email I sent Cøbra:
Hey,
FYI, the .org TLD was just sold to a private company.[1] I noticed
Bitcoin.org is due to expire in two years; you may want to renew now to
the maximum of 10 years before the new .org TLD owners raise
prices (some TLDs charge many thousands of dollars per year for the
"bitcoin" name in their TLD).

https://savedotorg.org/Cøbra replied thanking me for the tip and saying that he'd update both domains, although he wasn't sure it was strictly necessary (indeed, so far, I don't think renewal fees have increased much).
