I know of one organization that uses it to enable early release of a time-embargoed document to prevent server overload when it's released. Instead, everyone downloads the document in advance and they release the password at the release time.
Besides, he didn't suggest they bootstrap their own CDN. It could be as simple as creating a Cloudflare account.
Any further guesses as to how "important" the organisation is is pointless in the absence of understanding the actual use case.
