Adversary-in-the-middle attacks can strip out the passkey option from login pages that users see, leaving targets with only authentication choices that force them to give up credentials.

This isn't inherent to passkeys or the standard that they use. This has to do with the configuration of the service being attacked and the fact that once you've achieved MiTM, the sky is the limit for what you can do.

Passkeys use the same underlying protocol as hardware authentication keys (FIDO, not the YubiKey auth protocol) and should be roughly as secure and vulnerable as that type of MFA method.
