MDiscs are ISO rated for hundreds to thousands of years.

Rated for, but that doesn't mean they're all actually manufactured to that standard.
CDs were rated for like 50+ years originally I think. We found out real quick that was an optimistic number, especially when you buy the cheapest thing around.
The international organization for standardization has rated them for archival use in the hundreds of years. This is not a maybe and the Wikipedia page/link I shared above goes over the testing methodology
"Archival use" means a commercial climate controlled environment. Not a plastic tub in your basement or garage.
No one said otherwise
ISO certification does require a bit more effort than just the bare minimum necessary to legally advertise specific claims about a product.
That doesn't mean all M-Disc manufacturing is immune to shitty business practices of a manufacturer, but they do have to meet certain manufacturing specifications.
