Hosting large datasets can be expensive but the hosting for the danbooru datasets was not. It's "only" a few terabytes in size. A previous release was 3.4TB, so the latest is probably some hundreds of GB, to a TB~, in size larger. The download was hosted on a hetzner IP, which is a provider known for cheap servers. You can pay them $50/m for a server with "unmetered" 1gigabit up/down network + 16TB of disks. $600 a year would not be difficult.

I think people tend to wildly overestimate how expensive hosting a large dataset has to be, because of cloud.

If you only need a few terabytes, you can rent from Hetzner for more like <$20/month. Maybe <$10 at this point, if you are patient. And you can use the server for other things too, since it's a fixed cost, like your website or encrypted backups or other files you host. I spent a while figuring this out before I decided to do Danbooru20xx, to make sure it was very cheap. Given how my website has grown in size, and how absurdly exorbitant cloud bandwidth and object/hard drive space is, the Danbooru dataset was practically free at the margin!

Some people are, some people aren't. I'm not. (I have intellectual sympathy with EA, but not emotional.)

$600 a year is a lot of money..
