S3 is not where this belongs. Backblaze B2 would be better and cheaper (~$1428/month) and no egress fees due to Cloudflare bandwidth alliance, the Internet Archive also has a private offering [3].
If the journalist in question sees this, or someone knows them, I am happy to assist in a migration at no cost. If someone from Google sees this (HN Google support), it would be swell if the delete lifecycle could be paused while this migration is facilitated.
Rsync.net works out essentially the same ($6/month cheaper) on a monthly basis, but offers 10% and 15% discounts for 12 and 24 month options.
B2 does mention a "capacity bundle", saying 250TB/year is $19.5K - but that's $1.5K more than the monthly pricing for the same capacity so it doesn't seem like they have any meaningful long-term pricing discounts.
