Fair enough. It's just that I think something in the field that can do these things would be filling a need. And all companies have to start _somewhere_

But I agree, getting a promise of long-term availability from a new company is a bit rich.

Thanks for the info about GCP - I looked mostly into AWS glacier and I know AWS did not have a prepay offer.
