I agree that this is a sticking issue; most procurement offices have vendor/supplier questionnaires that ask about their cash flows etc., because companies want to deal with going concerns. FOSS without an org doesn't check that box.

BUT isn't this exactly the point of having a Mozilla Corporation, as separate from the nonprofit???

For smaller companies, or companies that want to invest less in their technology stack IT department, it sounds like a better deal to have all services provided and backed by a larger computation corporation (even if that's not always actually cheaper in the long run).
