I would actually be far more comfortable with storing my data for archival on CD-ROM or DVDs than BluRay, since the former standards have been publicly and freely documented[1][2] from the physical properties up to the logical bits and bytes, while I don't believe the same exists for the latter.
In other words, anyone can, with enough engineering resources, create a drive capable of reading those discs, which is more than can be said of more proprietary formats.
If you really need to read a CD-ROM then getting your hands on a SATA DVD-Drive, which usually are able to read CD-ROM, shouldn't be that big of a problem. Without looking hard I'd probably come up with 3 spare ones in my basement alone.
Tho I don't think that many of the self-burned CD's from 2 decades ago are still any good, I know mine usually ain't.

You'd be surprised. I went recently through several of mine and lo and behold they could all be read. I guess it depends a lot on your storage conditions.
I’m sure a graph of Time vs Value for data would have a significant dip shortly after creation, but on the scale of centuries it only goes up. (just look at the Dead Sea Scrolls).

Century? Startup sites like the one above last on average 6 months, that is, until they find out that their $6/mo DigitalOcean droplet suddenly costs... $10/mo! Or $100/mo or whatever and then they find out they cannot fund their $100/mo droplet and call it quits.
So... if you need the data to be around for 100 years, maybe not give it to the random startup.
Seriously. The only device I have which can read a CD-ROM is my car. The PS4 can read Blu-Ray and DVD but not CD-ROM.

Then I’d need to find a computer with a SATA interface... looking 10 years in the future it’d be even less easy.

In a century I don’t even think we’d have CD/Blue-Ray. By then most of us would be dead already, so why worry?

It's an open-source project that has been around for nearly a decade, not some new startup.
This project started development 8 years ago.
