It seems like a lot of your points hinges on this being true, but it simply isn’t.
“AFAICT” expands to “as far as I know”, which means the text that follows not an assertion. It’s an intuitive expectation that is open to be proved or disproved. The pins are all set up for you to simply knock down.
There is a massive benefit to preventing DDoS attacks, and that does not require keys.
This is unexplained. I’ve explained how CF uses its own keys to offer DDoS protection (they directly treat the traffic because they can see the request). I’ve also explained why CFs other (payload-blind) techniques are not useful. You’ve simply asserted the contrary with no explanation. HOW does CF prevent DDoS in the absence of treatment of the traffic? Obviously it’s not merely CFs crude IP reputation config because any website can trivially configure their own firewall in the same way without CF. So I’m just waiting for you to support your own point.
There is no indication that banks are handing over client ctedentials to CF.
This is trivially verifiable. E.g. if you get the SSL cert for eagleone.ns3web.org, what do you see? I see CF keys. That means they’re not using the premium option to use their own keys. Thus CF sees the payloads. I’m open to being disproven so feel free to elaborate on your claim.
That’s what I’ve been saying throughout this thread. The only significant DDoS protection offered by Cloudflare requires CF seeing the traffic (and holding the keys) so it can treat the high-volume traffic. If CF cannot see the payloads, it cannot process it other than to pass it all through to the original host (thus defeating the DDoS protection purpose).
Why would you need an account? Why wouldn’t bogus creds take the same path?
If it’s true that this is unverifiable, that’s good cause to avoid Cloudflared banks. It’s a bad idea for customers to rely on blind trust. Customers need to know who the creds are shared with /before/ they make use of them – ideally even before they make the effort of opening an account.
This uncertainty is indeed good cause to avoid using a Cloudflared bank.
UPDATE: I’ve spoken to some others on this who assert that it is impossible for a bank customer to know for certain if a bank uses their own key to prevent disclosure to CF.
