Let's be specific. Who is "they"? Who do you think is threatening to ban KeePassXC? A mid-level Okta employee? The whole FIDO Alliance?
Brother, there's no conspiracy here. Attestation requires a trusted third party, same as TLS. You know how you can generate self-signed certificates, but your browser and other tools don't trust them? Attestation is like that. What you keep calling a "ban" is a trivial operational consequence of this. Individual services still get to decide whether attestation is even required, and in the consumer space you aren't going to see it much.
